I keep having to start fresh with a new profile

Firefox Profiler

I use Firefox on all my devices, most of which are Windows 11. I use the same browser extensions and the same settings on all devices. On one particular device, a serious issue keeps happening (every two or three months in average). Suddenly Firefox starts hanging indefinitely upon launch, and has to be forcibly terminated. If I disable all the extensions, the problem is not solved. Firefox can start only in safe mode. The only solution I have found is to create a new profile and start all over from scratch. I need to figure out what is causing the issue in the first place, and then also a way to solve it without having to trash the profile. Thank you
