Sims 4 will not open after Windows Update

Product: The EA app
Platform:PC
Error Report ID (learn how to create an Error Report ID in the sticky post) None given
Which client functionality are you experiencing this bug with? Application Installer
When did this happen? (dd.mm.yy hh:mm) 12.01.24 14:30
Summarize your bug So today I started up my PC and was going to launch the Sims 4, only for EA to tell me I don't have it installed? I still have the icon and all of my mods and saves, which I backed up. I had to uninstall the game from the Apps & Features tab on Windows, and am now stuck redownloading the game and all the packs. I should mention that there's also no option to repair the game.
How often does the bug occur? Rarely (0% - 9%)
Steps: How can we find the bug ourselves? I'm really unsure what caused this, besides maybe an abhorrent amount of mods
What happens when the bug occurs? Game uninstalls itself after shutting down my computer the night prior, have to completely uninstall the game to be able to reinstall it, or else you get a 3-5 second loading animation where the installer usually resides and doesn't actually install anything.
What do you expect to see? My game to not randomly uninstall itself, I guess.

I have 110 GB free of space, fast internet (900 down, 30-50 up), and my specs are pretty decent (I'll put a full list below). Drivers are updated as well. I own most of the packs besides kits, Batuu, Home chef, Horse Ranch, and For Rent. I do have an ungodly amount of mods (roughly 37 GB) and also use shaders. I assume a mod caused this but I've never had a mod just cause my game to uninstall itself entirely, just have had it make the game not launch or cause in-game issues.
