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
Giovanni
