I have a problem in development of mixed reality app and there has been 2 days that I'm stuck.
My problem is that after adding packages of MRTK to the unity project, if I click the play button, the unity exits (closing) without any error massages or warning.
I tested two versions of unity (2020.3.32f1 and 2020.3.33f1) and both had the same problem.
I am using this link (MRTK document) and also this one Mixed Reality Feature Tool as a guide for configuration and adding the packages of MRTK to my project.
I have also tried two different versions of the packages i.e. (Mixed Reality Toolkit Foundation and Mixed Reality Toolkit Extensions both versions of 2.7.3 and 2.7.2 and for Mixed Reality OpenXR Plugin package I tried 1.4.0 and 1.3.1 versions).
I am using Visual Studio 2019 version 16.11.14
Inside Unity, I am choosing Universal Windows Platform from the Build Settings and I want to practice a little development of mixed reality applications, but I am stuck at the beginning and when ever I press the play button the unity exits (closed) without any warning or error.
Just for more information → I don't have Microsoft Hololens2, therefor I am considering to use Windows Mixed Reality simulator (Mixed Reality Portal).
I can't get what mistakes I am doing, please if you have any idea help me.
Thanks in advance.
There are many steps to configure a Unity Project for Mixed Reality. According to the description, it is hard to determine which step causes the issue. I have created a repository which is implemented with the necessary MR packages, and the configuration has been done. Feel free to pull the repo from https://github.com/sethdu0525/MR-Blank-Project. Please open it and click run to test.
If you still have this issue, you may need to have a clean installation of Unity 2020.3.33f1 (LTS), Visual Studio 2022 and make sure all the required components have been installed, including a comparatively new Windows SDK.
If you have a dump file for the crash, you may also share it and find support from Unity forum -- General Discussion - Unity Forum

About a week ago I opened shader graph in one of my projects when I noticed the connections between nodes are just gone (like shown in the image). The shader still works just fine as if the connections are there, but it's impossible to work with since they are not visible. Today I have noticed that the Visual effect graph also lacks the connections. The problem started on Unity 2021.3.6f1, then I upgraded to Unity 2022.1.22f1 and the problem remains. Even if I create a new project I still can not see any connections. I am working on Macbook pro 2017. Any help would be appreciated.
shader graph without connections
I tried restarting computer, reinstalling Unity Editor, downgrading to an older version of Unity Editor and creating a blank project but nothing fixed the problem.
I experienced this same issue in Unity 2021.3.11f1, and confirmed the bug in multiple projects that were previously fine (only one of which was recently changed).
What MacOS version are you running? My best guess is that MacOS Ventura 13.1 broke some versions of Unity, as upgrading from macOS Monterey was the biggest change to my system this week (2019 MacBook Pro 16").
The following steps appear to have resolved the issue for me (so far so good):
Reboot the computer (just to be sure)
Backup the project (I just created an archived duplicate)
Install Unity 2021.3.16f1 (the latest LTS release)
Delete the project library (in case there's something weird cached)
Open the project in the new version of Unity (which also regenerates the library)
I am now able to edit shader graphs again. Of note, deleting the library and regenerating in 2021.3.11f1 did not fix the issue. Only opening it and regenerating the library in 2021.3.16f1 worked for me.
I did not test leaving the old library intact while opening the project in the newest LTS version of Unity; it's possible regeneration isn't necessary, but it does seem like the safest bet. Especially if you didn't try removing the library before upgrading the project to Unity 20221.22f1 and you're still experiencing issues. You might try deleting the library to see if that resolves the issue now, without trying to downgrade to 2021.3.16f1?
There's a post over on the Unity Answers support site about this issue as well, but the login system appears to be broken (the irony!), so I can't respond there. https://answers.unity.com/questions/1927887/shader-graph-connections-not-visible.html
Can't build the project and use unity remote. What to do? Downloaded the latest 2020 LTS with a development package for android
External Tools
Unity hub
When installing a version from the Unity Hub, make sure you have selected the various android packages as you see in the image.
You have shown a link where you show that you did. If the procedure is the one I showed you above, you are not wrong.
Perhaps the problem may be related to Unity 2020.3.15 which in fact I do not find among the available downloads and which was released a few days ago. Maybe they caught some bugs (like maybe what you are showing), and took it out of the releases. Try downloading the 2020.3.14 version from the site (the one I use too), and see if the problem persists.

Trying to follow the Microsoft Azure Spatial Anchors tutorial (even after it was recently updated) but the Release build of the project crashes on launch on the device (just after the Unity splash screen). Interestingly a Debug build of the same project seems to launch ok.
I've been able to build, deploy, test both the basic Hololen2 tutorials and the ASA Samples as well as some custom projects so don't think this is a general development or deployment issue.
Have others been able to follow this tutorial and successfully deploy to a device recently and/or is there any suggestions to diagnose the issue further?
Setup and Unity packages used (as per the tutorial and linked instructions):
Hololens OS (up to date): 19041.1136
Unity 2019.4.19f1
com.microsoft.azure.spatial-anchors-sdk.core#2.7.1
com.microsoft.azure.spatial-anchors-sdk.windows#2.7.1
MRTK Foundation - 2.5.3 from the basic tutorial series (MRTK Package Tool)
AR Foundation: 3.1.3
Windows Mixed Reality: 4.2.1 (downgrade from 4.2.3?)
MRTK.HoloLens2.Unity.Tutorials.Assets.GettingStarted.2.4.0.unitypackage
MRTK.HoloLens2.Unity.Tutorials.Assets.AzureSpatialAnchors.2.4.0.unitypackage
Note: MRTK.HoloLens2.Unity.Tutorials.Assets.AzureSpatialAnchors.2.4.0.unitypackage listed in the tutorial actually links to a new 2.5.3 package (https://github.com/microsoft/MixedRealityLearning/releases/tag/azure-spatial-anchors-v2.5.3) however the version file in this package still has 2.4.0??
Exception thrown at 0x00000226E0FBCC40 in Workspace Hololens2 MRTK.exe: 0xC0000005: Access violation executing location 0x00000226E0FBCC40.
Have you tried to upgrade the ASA SDK to version 2.7.2 (https://github.com/Azure/azure-spatial-anchors-samples/releases/tag/v2.7.2)?
They have recently fixed an error exactly like the one you're reporting:
"The first bug was specific to ARM32 builds running on HoloLens 2 and was manifesting as an access violation crash in SDK during anchor creation or query."
I have the same Problem. Running it without the Debug Window worked for me!
I have used Rider in the past on Unity projects, there was a button to start Unity Play mode from the IDE, and attach the debugger. I am using 2019.2 version of Unity and latest of Rider right now.
I should have some icons like in the documentation here https://www.jetbrains.com/help/rider/Unity.html#.
Nothing show up, and the best I get, is Rider proposing to add a custom configuration... Rider is correctly set as the IDE for Unity in Unity preferences. I do not understand what is going on.
You should go to 'package manager' of unity and upgrade 'Rider package'. Then you have to go to 'preferences' and should see new option appears in external script editor in external tool option select it and your are good to go.
Installed Rider again, while checking every delete checkbox (cache and settings and more), did not re-use the config from previous version (see https://rider-support.jetbrains.com/hc/en-us/community/posts/360005280960-Cannot-attach-Unity-debugger), and also made sure I have Unity support checked. The button is back.
For me (MacOS) it was due to not having mono installed. I opened up visual studio community once, and it prompted me to install some tools. After that I rebooted unity and rider, and everything worked properly.
I'm new to Unity 3D Game Development and I've learned the very first game Roll a Ball by watching tutorials but in the end stuck in a problem that I am not able to Build my Project from the Build Settings PC Standalone Module, Error occurs:
No PC/MAC standalone Module loaded.
I don't understand where would be the problem, I have also attached the screenshot of my question.
As Droppy mentioned, it looks as though you are missing the Windows Build Support module.
However, you don't have to reinstall Unity, you can just run the Download Assistant and just select the Windows Build Module from there. That will install the module, without reinstalling Unity.
Close and reopen Unity, and it should work fine.
As described in the documentation, you can decide what modules to install when you install Unity. It looks like you didn't install the Windows Build Support module.
To rectify, I would recommend re-installing Unity (it's probably been patched since, anyway).
