"Continue" and "Load game" buttons disappear when I click them / Can't load game

Hello everyone

When I tried to start the game today I was suddenly unable to load into the game. The game starts but when the "Continue" button appears and I try to click it it doesn't do anything except for making all buttons disappear. So does the "Load game" button. All other buttons like the one to close the game or the "Settings" button work.

I de- and reinstalled the game, I let Steam search for any errors in the game files (it found nothing), I tried to create a new wgs folder (though I am not sure that worked), I restarted my PC...nothing worked. I am about to cry, please help me.

Thanks in advance
