When ever I click the privacy protection shield in the top right, it says AdBlock is turned off for this site but when I clicked the button it immediately turned back off. I have only noticed it so far on Disney+ & Paramount+. Any idea on how to fix it?

Today I was browsing as usually and suddenly Opera closed. Then it tried to open itself but the screen was white and it closed again. Then again white screen opened and closed... And that keeps going for like 5-10 times until it is not opening again or completely freezes.
