The issue came back after a couple weeks. Is there a more permanent solution than just clearing the cache?
Hey, everything good? So, this happens because of some issue with an extension installed on your Brave browser. In my case, here’s what I did: I kept one tab open with the messed-up YouTube and in another tab, I would toggle each installed extension on and off while refreshing the YouTube page. That way, I could figure out which extension was causing the error and removed it from the browser. Later, since it was a useful extension, I reinstalled it, and this time it didn’t cause the error that was happening before.
