I can’t reproduce this crash. According to some forums，UnityGfxDeviceW crash maybe cause by Multithreaded Rendering，and this bug was fixed in 2020.3.48。So I update to 2020.3.48, bug crash still exist, even if disable multithreaded Rendering.（ Most of crash comes from Android Simulator）
I try to find out root of problem, but crash trackback just one line stop at libc.so.
So I hava some question:
- Is this crash report correct ? Why trackback just stop at libc.so. How can i get more information?
- Is UnityGfxDeviceW problem cause by Unity or my script ?
