Is YouTube currently working for you?

@Antimalware18, I'm using McAfee WebAdvisor along with uBOL and have no YouTube issues on Vivaldi. This might be a region-specific issue; I am from India. Try clearing Vivaldi's browsing data. Vivaldi has a bug; it doesn't clear cookies when clearing browsing data. Use chrome://settings to clear browsing data.

Disable Vivaldi's integrated ad blocker within Settings and use only uBlock Origin

I had a better solution, I discontinued using YT and enabled built-in adblocker
