Object thumbnails error in Build mode

Hello,

Do you know why I’m getting this error? I thought it might be a mod, but I checked if there were any corrupt files (there aren't any), I deleted the Ts4script files and also tried deleting the localthumbcache.package file, but none of that worked.

I also tried removing the mods and then adding them back. Desperately, I uninstalled the game along with all the content and reinstalled it. It’s still the same.

However, I can still click and place it in the world without any problem. It’s just the thumbnail that doesn’t show, and I know that the last time I played, they were all showing fine.

Can anyone tell me what this might be and how to fix it?

Thanks and best regards."
