I'd recommend using the Adobe CC Cleaner tool to both uninstall and clean up after PrPro, reboot, then reinstall from the CC Desktop app.

I've tried as you've suggested, but the problem still remains on reinstall
Just as an update
I can view the same file on Android as normal, no green screen.
Some digging leads me to believe it's a Windows 10 problem.
I'm going to try out a few things and see if I can find a solution..
How are you viewing the export?
The Intel UHD Graphics 630 seems to be causing a green screen on both windows and in browsers when playing an HD video.
Solution: I’ve gone into Device Manager and disabled the Intel, my NVIDIA is still enabled.
Right clicking Intel-> update driver->browse computer->pick from list->MS Basic Display Adaptor, also has the same effect, if you don’t have a separate graphics card.
The display isn’t as crisp as the Intel, but I can live with it if it means I can view HD videos in browser or on the desktop without this green screen business.
