I remember watching films on Amazon Prime used to work just fine but it's been a few months since I watched anything and now, for some reason, it doesn't work anymore.

I hear the sound but there's no video - just black.

I tried Firefox, Opera and Librewolf - same Problem, so I wanted to ask here if the problem could be OS-related.

From the research I've done I found that apparently it could be something to do with hdcp copy protection, but I didn't get any error message in that regard.

Does anyone have an idea how this problem can be fixed?
