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
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.

I tried it by my self and it worked.
