Hi, our project uses Unity 2020.3.17f1c1 and has encountered a random crash on iOS. I googled these keywords “GfxVersionList” “~BufferMetal” but didn’t find any similar posts.
Here’s the stack trace:

So, I had the same problem on my project. Although this is exactly the error text sent to the crash analytics - the problem was a memory leak in the native libraries.
In my case, the problem was in haptic plugins (problem not solved yet), in some situations haptic could run very often and at a certain point used memory (not noticeable in the profiler) began to grow and, if spam haptic was not stopped, led to the crash.
I’m running into a similar problem myself.
I am using Unity version 2020.3.30f1

I tried so many ways and now i fixed this crash:
My solution:
Project Settings → Player → iOS platform (iOS Only) → Other Settings
- Untick on Metal API Validation
- Tick on Multithread Rendering
- Untick on Graphics Jobs (Experimental)
My crash-free rate inscreased from 98.8% to 99.6%.
I hope my solution will be helped. Good luck!!!
