Games using Unreal Engine 4 crash after a few minutes of playing

Recently I started experiencing issues with two games, Astroneer and Witch It, both use UE4, not sure what version.
Both games crash after a few minutes of playing and the UE error message pops up with the send crash report options at the bottom. I have updated my Nvidia drivers, I also used DDU (Display Driver Uninstaller) to make sure nothing was lurking around from the old driver.
When the games crash they freeze for a second and then goes straight to the error mesage, nothing unusual is happening in the games that I notice when it freezes.

Any advice on how to fix this/these issues are welcome.
