Full screen in YouTube and Vimeo does not work, black screen

In every video player I've tried online (YouTube, Vimeo, random new websites, Facebook, other video browsing websites) as soon as I hit full screen, the screen that the browser window was open on goes black. The audio is still present and the cursor seems to recognize and react to where the full screen interface buttons are (on YouTube, clicking in the bottom right hand corner exits full screen). This phenomenon occurs in both Google Chrome and Microsoft Edge. When watching videos on an offline player, such as VLC player, Quicktime player, or Windows Media Player, media plays in full screen just fine. The Windows "Movies and TV" app however also displays a black screen when put in full screen mode. The issue occurs both on the built in screen on my laptop and on the external monitor. I have reinstalled and updated Flash, my Nvidea driver, Google Chrome, and Microsoft Edge. I've run windows powershell and even reinstalled windows system files. Could this be a Flash player issue or and issue with my Flash player settings? If so, or if you have another idea, please help.

Thanks,

Michael
