All videos stop playing after 1 minute

I did a fresh install of firefox to try to fix this but it seems to be tied to my account. My browser has zero extensions installed and no custom settings. It's a clean install of a browser i've never had installed.

If i play videos on my main account (the one posting this question), all videos stop playing at 1 minute and i get the error “Something went wrong. Refresh or try again later.”

If i change account to another one, all videos play just fine. If i change to a third account all videos still play fine. If i switch back to my main account, all videos stop at 1 minute again.

If i switch over to the Brave browser i see the exact same behavior there.

I have followed everything under https://support.google.com/youtube/answer/3037019?hl=en&visit_id=638676896068092882-3016073081&p=videoError&rd=1#3rd_party&zippy=%2Cfelmeddelandet-n%C3%A5got-gick-fel-uppdatera-eller-f%C3%B6rs%C3%B6k-igen-senare and it does not help one bit.
