Black Screen every few minutes on all websites

I’m a new user and have just downloaded Brave a couple of days ago ( V1.19.86). I can be on Gmail, or Youtube or any website really, but every few minutes a black screen flashes over my entire screen (even over the fixed windows task bar of my Windows 10 Home OS build 19041.685), and then after about two seconds, it reverts back to what I was doing in Brave (resuming video, looking at website, whatever). This happens every few minutes. Help?

I’m having the same issue, and I made a post about it around the same time. Still waiting for answers.
