Windows 10: I randomly cant see thumbnails/icons of screenshots in file explorer. & cant see the thumbnails & icons of some programs

Question

So this issue has been happening for a week and half ago. I have a msi gl66 and one day I wasn't able to see the previews/icons of images in file explorer. It like windows lost it ability to make me view the preview thumbnails of screenshots. this is not only just for screenshots, also some programs too like NIVIDA control panel.

I tried a lot of stuff like.
1: Restarting my pc
2: deleting thumbnail cache
3: SFC. scan
4: Explorer>Options>View>Always

*display icons, never thumbnails (checked and unchecked)
5: K-Lite Codec Pack in the Start Menu, Codec tweak tool> thumbnails> unenabled and enabled

*
And I've probably tried various other stuff too that I've forgotten about.

Is there anything else I can check?

How exactly does Windows build thumbnails, is there some code, or a .dll file somewhere?

Does Windows handle video and image/photo thumbnails differently?

I also don't have any thumbs.db files, anywhere (is this even still a thing?), even in folders with photos and thumbnails in them, even though I have turned on the option to show protected operating system files and hidden files.

Anybody know what's going on here?
