Hello,
I am working on a small environment on UE5 while recording the process with OBS to make a time lapse. Everything was fine during the first days, then it started to crash over and over.
here is the log :

I tried to restaure NVIDIA settings to default in the control panel. I also tried to disable antialiasing FXAA, but it doesnt help.
my texture streaming pool size is set to 2000.
Do you guys have any ideas ?
