white screen after clicking new game/load game.

Every time I click new game instead of properly loading, it just loads onto a white screen and doesn't progress any further.

I feel as if I have tried literally everything. I removed every single mod and tried reloading the game. Same result. I repaired the game. Same result. I uninstalled the game and re-installed it. Same result. I moved the game into desktop. Same result. I'm at my wits end.

I truly don't know what else to do and following advice given to people who seem to have had similar problems to me hasn't helped either. I'm wondering if there is some other solution I haven't tried yet?

(I'm also on Mac if this bares any importance to my issue)
