I figured it out. I must have gotten banned by youtube, despite me having no youtube channel, so i cannot like or comment videos. Hence I could have not "behaved badly" by any means. I opened the incognito mode, where videos work, i signed in and then instantly videos don't play. I have youtube account solely to be able to follow channels and have a subscription feed as well as history for recommendations. This is the weirdest thing I have ever experienced with youtube. PS: and obviously this is the same with chrome-based browsers. It is my account that is the issue.
