Problem: After building and deploying, I get the following error:
E1696 cannot open source file "atomic_ops.h"
I tried all sorts of combinations including Release & ARM and Release & ARM64 but to no avail.
Without the debugger I can get it to start and display the scene but after a few seconds it crashes.
My scene only contains an interactable (grabbable) cube as shown here:
Here are the settings that I have in Unity 2021.3.22f1
I'll leave this image here in case it's of use:

Dear Stove, did you fix this bug? I have this issue but I could not fix it with changing the Unity Input System because its version was 1.6.1 for Unity 2021.3.27f1. Could you share your experience.?
Thank you.

Hello, Welcome to Microsoft Q&A,
It seems that Input system 1.5.0 is used by default in Unity 2021.3.22f1, which causes crashes, this is a known issue, please refer to Known issues in Unity versions and packages - Mixed Reality | Microsoft Learn. You can find this package in Unity Package Manager->Unity Registry and update it manually.
Also, regarding the packages in MRTK, you can refer to MRTK packages - MRTK 2 | Microsoft Learn to understand their usage, and then choose according to your needs. By default, only Mixed Reality OpenXR Plugin, Mixed Reality Toolkit Foundation and Mixed Reality Toolkit Standard Assets are required.

Hi,
I got the same issue above. When I ran the app in Hololens I got an empty dialog like this
I accessed the Unity Registry as you recommended but Input System was 1.6.1 as shown in the below image. Could you help me fix this issue?
Thank you,
P/S: I use Unity 2021.3.27f1 and Visual Studio 2019
Hi @ldluong , your question looks different from the original question in this thread, please feel free to post a new thread for your question. And please share more information about your project.
Also, it is recommended to use Visual Studio 2022 and create a new project to test, please refer to Install the tools - Mixed Reality | Microsoft Learn.

hi, I get the same issue, and I check the Input system is 1.7, and I have tried Unity 2021.3.30f1, 2020.3.33f1, but they both have this issue. And my MSVC is 2019. How to solve it? thx!
No, Wang, I got the same issue. If I did "Start without debugging, the app was deployed to Hololens but I only got the empty dialog like the above image. Everytime I touch the dialog, the app looks like opening or loading then return this dialog. I think it crashes.
When I debugged it, I got the same error "E1696 cannot open source file "atomic_ops.h" ".
In addition, I did install Visual Studio 2022 when I started working with Hololens but I couldn't build the app successfully. It might be that my Unity was originally assigned VS 2019, and there was a conflict between these versions. Then I had to uninstall both unity and VS and use the current configuration with Unity 2021.3.27f1 and VS 2019.
hello, I get the same issue with you, do you solve it?
