If you find your game either becomes stuck or crashes when attempting to Alt-Tab/Minimising to Desktop out of the game, please try the following:
Reinstall your graphics card drivers:
If this still doesn't resolve your issue, we'd recommend going into your in-game preferences and changing your display from 'Full Screen' to either 'Windowed' or 'Maximised Borderless Windowed' mode.
If this still doesn't work, we'd suggest making sure Steam overlay is disabled. Details below:
Turning off Steam Overlay:
Go to Steam -> Settings. Click the In-Game tab. Make sure "Enable Steam Overlay while in-game" is un-checked.
