Oculus Quest deadlock

Recently, we have been encountering significant problems that we are struggling to resolve. Our game on Oculus Quest 1/2 stops rendering new frames (screen lock) during gameplay and crashes. From our research, it seems that this is caused by deadlocks on the GPU. Here is the error code from Adreno-GSL that we are getting: 0x400c0907

Interestingly, the problem does not occur on all devices, but when it occurs, it is always on the same ones. Below, you will find a fragment of the crash log for you to see. Does anyone know what can cause such deadlocks?
