You may need to set r.ForwardShading to false in your DefaultEngine.ini

You can open your DefaultEngine.ini up by right -clicking the file and opening it with a text editor.

My 26th line of this file says
r.ForwardShading=True

Try setting it to: r.ForwardShading= False

Save the file.
Relaunch Unreal Engine and open the project.

Reference:

M1 Mac, Errors when opening VR Template: 5.3

I just managed to make a little bit of progress on this issue. I created a Virtual Production project, since it also supports VR stuff – or at least is used for VR-related production. This type of project opened! So, next I decided that I would maybe try copying some of the .ini files from the Virtual Production project into my VR Game project, and I was able to get it to open! However, it isn’t rendering properly, presumably because something is wrong with the RHI settings or something alon…

@r0bray

r.ForwardShading

Thanks! That works perfect!

Have you been able to do “vr preview”? The disabled option appears to me (in gray). If you have achieved it, could you tell me how you achieved it? Thank you very much and an apology for disturbing you.
