Re: [CURRENT ISSUE] Sims 4 DLC shows as installed, won't load in-game

I tried reinstalling and repairing the game multiple times. Neither starting with the EA App nor  Steam works. I own almost every pack except for some Kits and I wanna play with them and not just the Base Game. Ingame it shows that I have the packs but they are not available for some reason. Also I own For rent over EA but Sims thinks I dont own it and the other Expansion Packs I own over Steam. Both the installation folder and the other folder (with the saves and mods etc.) are completely fine as they should be. Is there anything that could help?
