OpenXR mode crashes after a minute

Windows 10 Enterprise

Ryzen 7 2700

Vega 56

Valve Index

16GB ram

 

Running Minecraft in OpenXR to play on the Valve Index through SteamVR works perfectly for a minute or so, then without fail crashes, it has been this way since at least 1.18. This is not a memory leak, and not an issue with SteamVR's openXR implementation as far as I can tell, as other OpenXR games do not crash. I've seen plenty of other people complaining about this, but no current ticket. Please fix the VR implementation.

 

Steps to reproduce:

Launch SteamVR

Launch minecraft using "minecraft://Mode/?OpenXR=true"

Wait about a minute and the game will crash, both in game and on main menu.
