Sims 4 saying I can’t place something in my own gallery saying I don’t own packs

I was playing my game last night and it crashed all of a sudden, which I haven’t had issues with in a long time. I reopened it and redid the stuff I had done and hit save but later it crashed again and then as I was trying to place a lot that I had saved in my gallery that I have used before a warning message pops up, saying I do not own pack items included in the lot and after hitting place anyway, nothing shows up and is doing the same again today. Has anyone else found a solution to this problem? I own all the packs I have gone in and double check to make sure they were all installed and they are. I just had this lot on my game until it crashed and now I’m saying I can’t put down any lot because I don’t know the items in the packs when I do. Any help is appreciated! I really don’t want to reinstall this entire game because I’m going to lose a lot of progress
