Extreme Game Lag After Removing All mods & CC

I was playing offline to avoid having to update to the March 17th patch, but my game and Lenovo Ideapad 3 were both insanely slow and I figured it was my mods so I removed all of them, cleared the cache and deleted the resource.cfg, repaired the game (which updated it lol), even started a new Sims 4 file entirely. My game is still so incredibly slow without any mods or cc that it’s too difficult to play. Camera rotation is twitchy and slow, Sim animations are extremely twitchy, opening any menu takes at least 5 minutes (it was never even that slow WITH mods) and hovering over UI options is so laggy that when I click on one thing, the game thinks I’m clicking where the cursor was 2 seconds ago. If it matteres, my CPU is running at 89%-93% just on the main menu… pls help!! 😭
