I had resolve 18.6.6 working perfectly but after updating the Win10 to 22H2 videos were no longer visible. I deactivated the license. Uninstalled and reinstalled it.
Still all videos are blank and only the sounds plays.
Any idea?
Thank you.

It suggests that you have installed the free and not the Studio version by mistake.

Thank You Charles,
I fixed this way: First I deactivated the hardware decoder in preferences and saw that even choppy the videos where no longer blank.
So I started the radeon software (I have AMD) which immediately gave me the warning below.
Clearly the windows update to Win10 22H2 made the old driver incompatible.
Then I ran the AMD cleanup tool and installed his latest driver via his autodetect adrenaline tool.
Now everything works fine. It was not necessary to reinstall Resolve.
Thank you again for you reply. Best
