no need to go that extreme, the fix is to just update ublock orgins filters

Go into ublock origin addon > click filter lists > purge all caches then update now

all done

Pi hole doesn't help, but there are various Android TV apps that do block ads. I still prefer the Roku eco system but I switched after they started putting ads in the middle of music videos.

If you have an Android TV, You can use SmartTube[1] that has Adblock + Sponsorblock

pihole doesnt work for youtube because ads and content are served from the same domains.
