Stop using random anti-adblock fixes you find on the internet, these are almost always out of date and interfere with the actual anti-adblock features in uBlock Origin.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. Purge caches and update filters
3. Reload the tab

And if there is not an updated filterlist, the anti-adblock does not apply logged-out at the moment, so you can continue in a private tab
