I’m sorry to hear that because I had similar problem but clearing cookies & cached web content option ended up working for me. Hope you find something that work because it was awful to experience ads after so long. I track stuff I subscribe to with TubeSync but still like to search for new topics & the ads were annoying.
Using Firefox and uBlock Origin, and following uBlock’s instructions re: resetting and updating. Getting timeouts and popups from YT regardless.
