Unity HoloLens 2 deployed App stuck loading

I am trying to deploy an app from Unity 2020.3.32f1 to the Hololens 2 with Visual Studio 2022 over USB. Everytime I try to deploy the app, it builds and deploys through visual studio correctly before it begins to load in the Hololens, it then gets stuck on 4 spinning spheres and remains here until I open the start menu and click home.
I have tried building an app following the process defined here https://learn.microsoft.com/en-us/learn/paths/beginner-hololens-2-tutorials/ and still end up stuck trying to load the app with 4 endlessly spinning white spheres.
I am using MRTK 2.7.3 & Mixed Reality OpenXR Plugin 1.3.1 installed from the Mixed Reality Feature Tool
Unity 2022.3.32f1
Visual Studio 2022
The previous project I was working with using MRTK 2.5.1, Unity 2019.4.28f1, visual studio 2022 and no OpenXR, with all the same settings works perfectly.
Below are the Build and Player Settings I am using
Build Settings
XR Plugin Management Settings
OpenXR Settings
This is fixed in Unity 2020.3.33f1 which was just released.
A workaround was given by disabling the Splash screen in the Unity Editor.
Here the release notes.

And the bug tracker entry.
https://issuetracker.unity3d.com/issues/app-doesnt-launch-on-hl2-uwp-after-update-to-2020-dot-3-32f1
I tried it by my self and it worked.
My Environment:
Unity 2020.3.33f1
MRTK 2.7.3
Visual Studio 2019
OpenXR Plugin 1.3.1
XR Plugin Management 4.2.1
I have this exact same issue. Same version of unity & using Visual Studio 2022. Everything was working with Unity 2020.3.20f1 => Upgrade to 2020.3.32f1 and the problem (infinite loading spheres) occurs.
Reverting back to version 2020.3.20f1 & clearing the build folder has fixed the issue for me.
Apologies for not giving any understanding as to why this may be occurring, I can only inform you that reverting to a previous unity build will more than likely fix the problem (As you are probably aware).
Same here, Unity 2020.3.32f1c1

strange gradle files from 2017 and lack of gradle in android studio

There were no flutter folder structure in my dart projects. here is how it looks I realized i dont have gradle in android studio. android studio preferences
I ran the terminal to be sure. terminal prompt
Then i search it in finder. I found gradle folders inside flutter first. I scrolled down and see the last one dates back to 30th november 2017
which is strange because I bought mac in 2020 and installed flutter on 15th February 2022. My mac is MacBook Air 2017 and the version is monterey 12.2.1 2017 folder is at the bottom I scrolled down a little bit more and saw there is gradlew and gradle wrapper created at 2017. strange gradle files
and their path were
gradlew:
/Users/kocel/tools/flutter/bin/cache/artifacts/gradle_wrapper/gradlew
gradle-wrapper.jar:
/Users/kocel/tools/flutter/bin/cache/artifacts/gradle_wrapper/gradle/wrapper
I had too much struggle during installation which i mentioned in here: Flutter - 'Xcode installation is incomplete', Missing CocoaPods installation and maybe the main problem was that strange files. Any idea?

Can't build Unity and Run UWP to Xbox One VS2019. Problem with Build tools

I'm trying to port my Unity 2019.1 created Steam and mobile game to Xbox One and UWP. I can create a VS project and build and deploy to console. Running "Build and Run" from Unity 2019.1 throws up this error:
D:_Programming Stuff\Unity\output_Data\ionAXXIA_UWP\Il2CppOutputProject\Il2CppOutputProject.vcxproj : warning : The build tools for Visual Studio 2017 (v141) cannot be found. Install Visual Studio 2017 (v141) to build using the Visual Studio 2017 (v141) build tools.
Is it possible to Build and Run from Unity to Xbox console, and if so, what do I need to do to fix this error?
Dunno why I was downvoted. Turns out it was a bug fixed in 2020.1.0a4, 2018.4.10f1, 2019.2.6f1, 2019.3.0b4. So 2019.2 and 2019.3 were fixed but 2019.1 wasn't. A project migration to 2019.2 fixed the issue and didn't cause any other problems with my project.

holotoolkit failed to build

I'm trying to build an app for hololens, impotring the holo toolkit, and make the build. this is the result:
any idea?
There are install instructions for MRTK here https://github.com/Microsoft/MixedRealityToolkit-Unity/blob/master/GettingStarted.md. That is the best place to get started, make sure you use the version of unity specified (although it will officially support 2018.1.9f1 with the next major release, and most 2018 versions do currently work, the current supported version is still 2017)
