What is 'Context Corruption?'

After the character selection, and shortly after the loading starts, game just crashes over and over again, with this ‘Context Corruption’ popup. What does it mean and what should I do with it?

Have you tried any of these fixes? I would start at the top and move down.

This is happening to me aswell ever since Quantum Ciara dropped ive been unable to play a single game until i verify the steam cache i get to play a single game then the game screws itself again and i cant play another game till i do it again
