Please try the following:
- Please copy the Mods folder from your 'The Sims 4' folder to your desktop (for future reference) then delete the mods folder and the localthumbnailcache.package file in your 'The Sims 4' folder and restart the game and so that the game will re-create the folder.
- Then run a game repair [ Open Origin, click 'Game Library' then right-click Sims 4 > Repair Game ]. After that, please see if the issue has stopped.
(If It fixes the situation you can re-add your mods/cc one at a time to see if one was conflicting with the function/causing the glitch - but do not re-add the old config file from the old mods folder, as it is possible for it to have become corrupted also.)
