My UE4 game crashes with Assertion failed: !AllocationFlags[Index]

Hello,

Been working on a game for Quest a month now and started to have a very strange issue. Sometimes when I run my game after loading it to Quest it simply crashes and drops me back to the menu. It seems to happen at random, meaning sometimes I can play for 10 seconds, other times for 30 min.

I keep getting one of these two errors:

I thought I coded something funny. So started a clean project and still getting the same issue.

Configuration for the project was followed by this video: https://www.youtube.com/watch?v=jlcj4HB9LX8

this issue was encountered by numerous other people as represented in this ticket: Unreal Engine Issues and Bug Tracker (UE-73467)

I don’t know what to do anymore. Running a clean project and still getting it. Any suggestions, ideas, debug ideas are welcome!

Thank you!

Anyone have ANY idea?

Here’s a strange thing: if for the first minute after starting the game I move very slowly it seems to work after then fine!

I’m trying to roll this ball a little further over here: Has the thread-safety of Map/Set changed since 4.19? - Platform & Builds - Epic Developer Community Forums

I also get this crash when testing on the Quest, but it doesn’t crash in a shipping build.

Seems like it’s fixed: Unreal Engine Issues and Bug Tracker (UE-73467) and included in 4.23 branch!
