I have the exact same issue using 3060ti, ryzen 5 3600 on Quest 2
The Registry work around sometimes allows me to open Minecraft if I use the shortcut discussed above, but only 1 out of 5 times it will open (normally crashes) and even if it does open with OpenXR it usually crashes within a few minutes
With the Oculus Link I just have the "Checking for Updates", followed by a black screen, and then the oculus link home screen as it crashes.
I bought Minecraft just to play it in VR, still looking for a fix
Finally! Someone from Mojang is on the case!
I am using the bedrock version of minecraft purchased and installed from the Windows Store last week
On the Oculus app I have then installed their Minecraft app
I am using a Quest 2 with a link cable, connecting to my computer running a 3060ti and Ryzen 5 3600
Steps:
I connect my quest via link
I open the Minecraft app
A 360 view of a Minecraft world of the app launches with "Checking for Updates" on each 90 degree side of it
3 seconds later the screen goes black
The Oculus link menu re-opens
I try this again and again with the same crashes happening
Troubleshooting steps:
Factory reset my Quest 2
Switch my computer off and on
Uninstalled and reinstalled Minecraft from the PC
Uninstalled and reinstalled Minecraft from the Oculus Store
No matter what I do the same issue happens. And it seams that it has been happening to many other people (see all the comments above)
