The old "Thumbnail" problem

I know this pops up every year, I just can't find any of the threads relating to recent versions.
I've been using Painter 2023 for months now and I figure it's safely time to uninstall Painter 2021.
In doing so Windows 10 loses its Riff thumbnails.

Reinstalling it I get my thumbs back. If I select "always open with Painter 2023" I lose them again.
Current workaround was to reinstall 2023 after reinstalling 2021, so the files open in 2023 while maintaining the thumbnails provided by 2021.
It seems a bit inefficicient to keep the older software on the computer just for thumbnails though!

Any thoughts or possible solutions?

Best wishes,
