Bug Game built with Unity 2019.4.28, crashes in vulkan.so library, but I'm using OpenGLES2/3

I built a game with Unity 2019.4.28 with OpenGLES 2/3 chosen for the graphics API, but I've been getting some weird crashes recently.

libunity called 'EGL_ClientWaitSyncKHR' of 'libGLESv2_samsung.so', and finally crashed in /vendor/lib64/hw/vulkan.samsung.so.

Currently only appears on Samsung S22, and the crash rate is relatively high, reaching 600/4100.

The following is the wrong stack information:

Added: It looks like it will only appear on Samsung S22 devices

 

Solved!

I found out that this is due to an incompatibility between Adaptime Performance and Unity 2019's Optimized Frame Pacing feature.

I found the following instructions in the documentation (https://docs.unity3d.com/Packages/com.unity.adaptiveperformance.samsung.android@4.0/manual/vrr.html):
Adapitve Performance and Variable Refresh Rate is not compatible with framce pacing and we recommend to dissable Optimized Frame Pacing under Edit > Project Settings > Player > Resolution and Presentation.

 

I' using Unity 2021.3.14f1 and I'm not using Adaptive Performance but I have the same crash on S22, S22+ and S22 Ultra devices with GFX: ANGLE (Samsung Xclipse 920) on Vulkan 1.1.179.
I do use Optimized Frame Pacing.
