After changing Minecraft URL to get VR working via "minecraft://mode/?OpenXR=true". The game will crash after a few mins in the main menu due to a massive memory leak. I got to play for about 5 mins until all 32Gb of my system ram was filled up and crashed.

This has nothing to do with Oculus version of Minecraft. I'm talking about Steam VR/OpenXR with memory leak. so don't mention this is the same problem as MCPE-16946 . The MCPE-16946 Talks about the game not opening and a completely different than a memory leak crash.

The game opens just fine but once your in the main menu of Minecraft. The memory usage will just keep going up until you run out of system memory. Then everything crashes due to the memory leak. I made a video showing the crash and have an on screen resource manger to watch the ram keep going up and up until the game crashes.
