VR Preview freezes with Environment Depth Start

I have tried a few times to get my VR Preview to work when calling the "Start Environment Depth" node in blueprint at the start of my project, however every time I do, the vr preview is just a white screen and freezes my entire project forever and the only way to fix this is my ending the entire unreal task.

 

I was able to at least find through the debug window that when the white screen is showing, its printing "{WARNING} [MRAPI] Long waiting time for depth layer creation." 

 

Is there any way of getting this to work as it would be annoying to have to do a build every single time to test small things.

 

For reference, I am currently using Unreal Engine 5.5.4 with Visual Studio Version 17.13.5

 

Thank you in advance.

      I'm also having the same issue. All I'm doing is following https://developers.meta.com/horizon/documentation/unreal/unreal-depthapi-occlusions-get-started

      So i explored the source code and when you try to debug the project it wont build because theres like 50 errors in the environment depth script which must be contributing to the freezing. The script is called OculusXREnvironmentDepthExtensionPlugin.h/.cpp But along with that, there are 112 errors thrown from all over the source code. Idk why they'd release something that is so clearly broken. Meta Devs please help
