Brave freezes and crashes

from few days I have some issues with browsers - and I especially mean “browsers” because it concerns both Brave and Microsoft Edge.

for what’ve observed it happens while using bigger sites like youtube, netflix and facebook, mostly while trying to play some videos and opening messenger, for example. I’ve tried to erase cookies, etc - didn’t work. It also happens in private mode if that’s relevant. Tuning off extensions also didnt work.

The browsers freeze and sometimes unfreeze after about a minute or longer. If it won’t unfreeze I need to close them with task manager and after that I can’t start them until I kill all of the processes.

Any ideas what could be causing that?

UP. Help pleaseeeeeeeeeeeee
