blue square glitch error
Okay so today I was cleaning up my mod folder and when I went into my game it had a hard time loading. It was stuck on the loading screen. I restarted my game and it finally loaded. After that, I went to click on a household and it's just a flashing blue box. (picture down below.) I can't play with the households either. The only thing I can do is create sims or build things, everything is perfectly fine in build mode. I tried creating a sim into a new household and when I was done it wouldn't load up and an error message popped up. (picture down below.) I also wanna mention that I bought an expansion and game pack the day the new update came out. I'm not sure if that has anything to do with the problem though! Even with taking my mods out of the game, it still had the same issue. I've been having problems with glitches since the update came out but this blue box thing just started yesterday.
Here's a list of everything I've tried to do in order to fix my game!
-I've restarted it multiple times.
-I restarted my laptop.
-I've uninstalled and reinstalled it.
-I took my mods folder out and put it in my desktop.
-I took out all of my broken mods and updated the ones that could be updated.
-I tried clearing the cache.
I'm not really sure what can be done to fix it, but I would really appreciate any help! Because I just bought new packs I've been really excited to play so this has been a bummer. ☹️
