After Opera has updated to version 67.0.3575.53 videos stopped playing and giving "html5 video not found. Nothing about my system changed in any way except for Opera updating. I have tried disabling Adblock and cleaning cache and cookies it did nothing. I also tried to turn off acceleration it didn't work too.I did roll back the version to the old one and it was working but now it auto-updated again and it doesn't play videos anymore, so it is problem with an update.

Plz someone inform if has a solution to this problem
Thanks
