Screenshare Problem.

I'm using a web browser called " Opera GX ", I never had issues like this before. But suddenly, I don't know if it's discord itself or the web browser. But, everytime I stream either Youtube, Netflix, Hulu after moving to another application.. The screenshare goes black for people who are unable to see the images... It shows this whenever I go on live after switching to another program.. It never done this before and I tried everything to fix it, but nothing is resolving itself.
