Creating outfits for a Getaway breaks game UI and controls after exiting CAS

I tried to schedule a getaway from the calendar and wanted to set custom outfits for the various roles. I did the first one (male Sim) without a problem but after creating the second outfit (female Sim) when the game exits out of CAS the getaway interface is blank and I can't use the mouse to click anything. The cursor still moves and the keyboard worked normally.

I play on PS4 so I tried using the controller instead to see if this fixes the problem, but again even though the pointer would move I couldn't select anything. There was also a blank pop-up when I was using the controller over the confirm icon which was blank (see image attached). I could use the controller to navigate through the UI to save and exit to the main menu but the issue was still occurring. Reloading the game was the only way I could bring back the pointer controls for both controller and keyboard/mouse set ups.

On my second try, after this happened, I went to the calendar and if I selected to create an event, there was another pop-up but this one said "Game Loading is in progress." which is most likely the causIng the problem (see image attached). Using the controller or keyboard I could still pause, change the game speed, toggle selected Sim, control the camera and enter build/buy mode. The pointer still moves around in whichever mode I played in, but I couldn't select anything and the hovering outlines and pop-ups didn't appear.
