Hello everyone,
Since a vew weeks Videos on sites like Crunchyroll and Wakanim do not load/play, but they still work on youtube.
My Opera Version: 80.0.4170.63
My Windows Version: 21H1, Windows Home (the normal one, not the "N")

I tried to deactivat adblock and hardware Aceleration, but it made no difference. I also made a clean profile folder but that also didn't work. Installing older versions of Opera made no doifference either. Deactivating my antivirus also changed nothing.
Using Microsoft Edge or Vivald to play the Videos worked, but I would like to continue to use opera.

I would be really nice to get som help, because so far i could not find something that worked for me.
