Trados 2024 File thumbnails do not show

I purchased Trados 2024, and all the files (.sdlxliff, .sdlproj, .sdltm, .sdlppx,.sdlplugin, etc.  ) are now shown blank. I cannot open them by double clicking.

When I purchased 2021, I don't think I did any set up change, but the file thumbnails are shown and I could open them from the folder by just double clicking.

Please advise what to do.

Best,

Kei
