Return of Reckoning

Hi, while I'm playing, if I have to go to the desktop for example to change the discord channel, the game crashes.
I always open the game as an administrator. I also tried to change the setting from 32bit to 64bit but the situation does not change.
How can I solve the problem?
thanks a lot

Try playing in Windowed(Fullscreen) rather than Fullscreen and seeing if that helps.
