YouTube Not Working? It Is Probably Your Ad Blocker
Many people are experiencing problems with YouTube showing an error message instead of the video. Usually this is caused by an ad blocker browser extension.

I determined this myself about five days ago, getting rid of Ad Block & all its associated files fixed my issue.
Funny thing is if you have a problem with that in Safari just use Brave ( which blocks all ads) and it works just fine.
Bill: But if everyone uses ad-free browsers or ad blockers, the content you like will soon disappear.
