Game crashes on "switch to fullscreen"
 

Clicking "switch to fullscreen" crashes the game with an error message, as does switching to higher resolutions.

One of my systems just started doing this as well. I have tried changing different setting, resolutions, etc. No luck.

What is the error message exactly?

edit: you may find something in these results.
