Start Up Pop Ups Frozen

Hi, to start this off- I have updated all of my mods, removed them and added one by one to see the issue (didnt work), deleted cache files, deleted save files, repaired game- and this is still happening.
When I start my game, the event pop up is glitched- it closes, next is another pop up which is seemingly invisible apart from the x- it wont come off even if I click esc, I'm having to use task manager to close the game. What else can I do?

I have attached photos of the issue, then of my mods folder although I have removed everything and added back in, then of my Sims 4 folder. Last exception isn't telling me much, I will include that if needed.
