Stop using random anti-adblock fixes you find on the internet, these are almost always out of date and interfere with the actual anti-adblock features in uBlock Origin. YouTube is changing their anti-adblock code multiple times per day.

Simply do the following:
1. Use uBlock Origin and no other adblocker. This includes disabling adblocking in "Enhancer for YouTube", and any built in browser blocker
2. In uBlock's settings, purge caches and update filters

@sponsorblock "anti-adblock" is functionally a double negative, and as a result I have no idea whether you're talking about measures to block ads or about exempting specific sources from your measures to block ads.

"Anti-adblock fixes" are measures taken by web users to counter websites' anti-adblock techniques, so the full phrase is effectively a *triple* negative.
