Adobe Bridge 2025 doesn´t show thumbnails for MP4 (video) files anymore? Why??

Hi guys, question: Why does Adobe Bridge from version 2025 not show thumbnails/previews for the MP4 (maybe other rich media files with video content)? It was so a handy/useful function, and it really works well. I didn´t change anything in the production chain, taking video the same way as I did before, and it stops working and displays just an annoying icon of the player instead. I tried to clean up the cache (Purge cache for selection) as well as to reinstall HEVC codecs in Windows, but nothing helped. Is there any reason why this stops working? Thank you very much for the answer. Have a nice day 🙂

Configuration: PC / Windows 10 fully updated / Adobe CC 2025 all apps / GPU Nvidia - drivers updated as well.
