Question Thumbnails Size Problem (Reverts back to small after some time)

Hello, I'm having some problems with the thumbnails of 2D Textures (it also happens with meshes and other things)

They are shown like this:



As you can see, many of them are so small that you can't tell easily what you are selecting, but some appears as they should, the thing is, if I right click those textures (or the entire project textures) and Reimport them, they get fixed, but only for a small amount of time (1 min to 30 min) and randomly revert back to small.

I'm using Unity 2022.3.6f1, has anyone encountered this issue or knows how to fix it?

Thanks.

 

Would love some help, this is very frustrating, thanks!
