I am sorry that you are having game issues. It would be best to moving your whole mods folder to the desktop.. Remove the localthumbcache.package file from the Sims 4 folder.
Then start the game and test to see if that helps the issues. If it does help, then put your mods/CC back into the newly generated mods folder in the sims 4 folder one by one or in batches and testing the game after each one to see which is the cause of the problem. Put one item or batch in , test the game , take it out. Then test another one, to find the cause of the issue.
Don’t save your game when testing. If you don’t save your game when testing, then the cc will remain on your cc after you finish testing.
