Sims 4 only opening is background processing!!!

Hi! This is my first time using this forum. Today my sims is having the issue of running in my background processes. I've been scrolling through old solutions for probably the last hour now? I've tried repairing, reinstalling, and clearing cache of the EA app. I've also tried rebooting my actual laptop multiple times. I've only had this issue today for the first time, yesterday it was working correctly. I've tried removing my Sims 4 folder from the Electronic Arts and running it and it worked! So then I tried slowly moving my custom content back into the game, and this is where I experienced the issue. I've spent another hour testing every single piece of custom content and all of it causes my game from running fine to running in the background. I'm not sure what else to do, please help!
