MRTK 2.7.3 - Outline Shader is not visible on HoloLens - unity3d

I saw the scene OutlineExamples in the MRTK examples package and recreated it in my own project.
The outlining works if I stay in unity in play mode. But if I deploy it on the HoloLens the object does not get a outline effect.
The OutlineExamples scene from the MRTKHub-project works as excpected on the HoloLens!
So I guess I missed something in my own project, but I cant find it. I compared the setup multiple times, but cant find a difference. And I also used the simplest object (the cube) from the example scene.
Setup for the cube
(the screenshot shows on the left side my project and on the right side the mrtkhub-project):
Mesh Filter (standard)
Mesh Renderer (standard)
Box Collider (standard)
MeshOutline with the Material "OutlineOrange" or "OutlineGreen" (added)
Object Manipulator (added)
Constraint Manager (added)
The only thing that I had to setup after adding the as "added" marked compenents, was the material for the MeshOutline component.
Is there something else someone has to setup to see the outline shader on the HoloLens?
My Setup:
Unity 2020.3.30
MRTK 2.7.3
Visual Studio 2019
What else did I check?
The XR Plug-in Management is set up the same way
--EDIT
I noticed something strange and I guess this will help someone who knows more about shader!
I launched my application on the HoloLens, grabbed the cube and put it in front of a window in my room. While placing the cube in front of the window, I saw the outline! But as soon as I move it outside the window area, the outline disappears! Another aspect is that I'm using the spatial mapping from MRTK. That means that the window does not get meshed, only the walls. And I guess the walls have their own shader on it, right?
So the spatial mesh shader and the outline shader "dont like each other". Is this possible?

The user derHugo gave me a hint that led to the solution! I went to the material, that I use on the cube and changed the property Render Queue Override under Advanced Options to a higher value than the material MRTK_Occlusion, which is used for the spatial mapping, has.

why my skybox disappeared after I added the urp package?

I want to add light2d to my project, but it's a decision I made after months I started the project, so then I added the urp package.
But something strange happended: my skybox disappeared. I mean, it can't display neither in my scene view nor game view, it seems it's totally transparented instead of a material error.
I have checked my lighting settings and camera settings, but there's no problem.
I tried to restart Unity editor, but it can't solve the problem.
Sorry for poor English, hoping you can read this.
If you use a "URP Asset (with 2D Renderer)", it wont use the Skybox material set in Lightning -> Environment.
Its probably by design i guess (2D dont need a "box", instead a rect will suffice).
Use the other Asset (with Universal Renderer) or set your "Skybox" as Sprite material in the scene.

Hololens + Unity: GameObjects are invisible

After I build my Unity project and send it to the Hololens, I have the following problem:
The splash screen appear followed by a debugging window on the bottom. In the background is a white net. However, you can't see any game objects. I've tested a lot but haven't found a solution for that. Visual Studio does not display any error messages. What I've looked at roughly:
These are my modules. Im using the 2019.4.22f1 version of Unity and the MRTK Foundation Toolkit 2.7.2.
My build settings
My project settings
I tried to place the objects in the middle of the camera and changed the colors.
MRTK settings I haven't changed anything most of the time
Main camera settings
My scene
When i start the scene i get this error in the console. I dont know if this has anything to do with my problem
i have two possible solutions (no guarantee)##
you could spawn the objects on input directly in front of the
camera, add a debug.log("object in front of you"); so you can find
the issue.
If this doesnt work i would try to test differnet types of materials
like you do with HDRP.
if this does not work either i probably cant help you out now.
It seems like your GameObject is too far to be hidden behind by the mesh. Please make the spatial mesh invisible by setting the Display Option property of Spatial Mesh Observer Setting to None, this item can be found under the Spatial Awareness profile of the MRTK profile.

Cannot Animate Interactable Gameobject using Mixed Reality Toolkit

I am a bit of a novice with the Unity Engine and Mixed Reality App development so please bear with me.
I have been working with the Microsoft Mixed Reality Toolkit for Unity to try and animate a game object and move it to the side. A simple action, very similar to an example scene provided by Microsoft with the toolkit called "InteractableObject" (Information links provided below)
Interactable Object - Mixed Reality (Microsoft Docs)
Mixed Reality Toolkit-Unity Interactable Objects and Receivers (Github)
This example scene in Unity has multiple objects to be used as "buttons". With the Mixed Reality Toolkit, even objects that you want the user to interact with to perform some sort of action when selected is even considered a button. At least according to the documentation I have actually been able to find on the subject. This is a series of screenshots depicting the inspector panels for my GameObject and the container for my object:
GameObject Inspector Panel
GameObject Container Inspector Panel (Part 1
GameObject Container Inspector Panel (Part 2
I am trying to make a single game object move to the side when I place the standard cursor on it. This same action is done with a balloon object in the example scene I mentioned. I have created the animator and the state machine the same as they did in there example as well as setup my game object in an almost identical format. Only real difference is that created a balloon object themselves and I am using a different set of custom models from my company.
When I attempt to play back the app in the Unity Editor, the state does not change when I place the cursor on the object. I can force the state to change using the editor and the required animation engages, but it will not change the state on its own. I configured my state machine the same as the Microsoft example and setup my state variable the same as well. It should move from an "Observation" state to a "Targeted" or "ObservationTargeted" state when the cursor moves onto the object. A screenshot of the GameObject state machine and the inspector panel of the specific transition in question are provided below:
GameObject Animator State Machine Setup
Observation to ObservationTargeted Transition Inspector Panel
I went through and verified that all components added by the Mixed Reality Toolkit are the same and they are. This includes the DefaultCursor, InputManager, MixedRealityCameraParent and Directional Light. I also checked that all the scripts were coded the same as well and they are. I am running out of places to look. I attached the Visual Studio debugger to the project in Unity and have verified that it just isn't changing the state on its own. But I cannot figure out why. I believe the problem has something to do with the setup of the transition, but I haven't been able to find the issue. All of the other mentioned components are provided by Microsoft and are not changed by myself nor are they changed in the sample scene.
If anyone else has had a similar problem or may know where I can look to find the problem please let me know. I haven't even built the project into an UWP application yet.
I know it's been a few months, but do you still looking for the solution?
With the newest version of Mixed Reality Toolkit you could make any GameObject to act as a button. Simply read this documentation. I have some cubes as buttons in my Unity project and the only extra Component I added to it to make it work was Interactable, which comes from Mixed Reality Toolkit.
If you want to trigger some animation when you place the cursor on the object (or look at it if you're going to use it with Hololens) then you can add them in Interactable object by adding a new Event (for example: OnFocus() event)
Hope this helps is any way

Unity materials appear broken

I've recently imported a Unity project that references .fbx file.
When I imported the project (which was created by another user) all surfaces are pink.
Having looked at all the materials the following is observed
All the materials in the top level materials are present but are shades of grey not as the material should appear
At specific assest level (assets->material_name->material) there are no materials
All textures are present
All objects have a material associated with them which are all from the grey materials.
I can force change a material by selecting the surface and manually changing the material from its default to the one material which isn't grey "teleport" for all three surface materials.
There is a seemingly related error at the bottom "speedtree materials need to be regenerated". I've googled this however, the only solution was to select the prefab option in the assets list which is not an existing option in my project.
Any thoughts would be awesome.

This is a shader problem. Please note that shader is not the-same as material. You plug shader into a material. The circled image below shows a "Standard" Shader that is attached to a material named "CubeMat2".
The imported Object can be pink because:
1.The shader is missing in the Project.
Manually copy the shader into your project and re-attach it to your material.
2.The shader is obsolete or uses a keyword that's not available your current version of Unity.
Make sure you are using the-same version of Unity "another user" used to create the original project.
3.A simple import bugs. This happens somethings.
All you have to do is select the material, change the shader to another Shader then change it back to what it was before. For some reason, this seems to fix the issue.
4.There is an error in the shader. If there an error in the shader, Unity can't compile it and it will be pink when attached to a material. Also, if there is a shader error, you will see that in the Console tab. You will have to fix that error.

NavMesh baking finished very quickly and does not include some objects

I am doing one of Unity's official tutorials: Survival Shooter.
Unity version: 5.3.4f1 Device: Macbook, OSX 10.11
http://unity3d.com/learn/tutorials/projects/survival-shooter/environment?playlist=17144
The problem: Baking process completes almost instantly and the floor is not highlighted by a blue mesh (where highlight should mean that navmesh is calculated for there).
Here is the screenshot of it:
Then, I checked the completed scene (which was already created by Unity Team), it showed the floor fully highlighted. I just hit the bake again without touching anything and the same problem happened. So, there must be something else as I tried the original scene file without changing anything.
What am I missing here? Is there a Unity editor setting or something like that which can break the baking process?
When baking a NavMesh for your game, a crucial thing to verify is that every object which should affect navigation is marked as a Static GameObject, or at least Static for Navigation. This setting may be found in a checkbox/dropdown at the top of the properties Inspector:
It sounds like the floor object in your scene hasn't been marked as Static, meaning it won't factor into the NavMesh baking.
