Help! Sims 4 keeps reloading and won’t connect with my computer mouse

Hello,

ever since the most recent updates, I cannot play sims 4 on my computer anymore. It won’t let me use my mouse and freezes unless I exit (sec key) and then click the icon to load back in. 

I can’t use my Bluetooth mouse of the mouse on my keyboard. I’d love some assistance, I’ve uninstalled, reinstalled and repaired the game and nothing is working.
