@jorianv Hey there, sorry to hear you're encountering this issue with crashing when you try to alt+tab back into the game.
I would first suggest making sure your graphics drivers are updated, as having them out-of-date can cause similar crashes.
If you still encounter the problem after that, I'd recommend checking out our PC Troubleshooting guide.
If after you've gone through the steps, you're still having issues with crashing after alt+tab, please reach out to us via one of the methods below with copies of your MSINFO and DXDiag.
