Android studio hangs with no reason

Question

I have worked on a project for weeks now on android studio but few hours ago android studio just hangs with no abvious reason. I restart it, I restart the PC, I did "Invalidate Caches / Restart". I search for solutions on google but no luck specially that I don't know what's the reason.

when I open Android studio it open the project but after a few seconds it hangs even if I don't do anything at all.
