All said, the error that the OP is getting seems to be that the (UMD) graphics driver is crashing for some reason. The first thing I’d try is completely uninstall the current driver, and then do a reinstall using the latest driver (if you get the option, such as with Nvidia drivers, tell it to do a “clean” install which will reset any customized settings).

I’m wondering when this happens, does the screen flash or briefly go dark for a second? That’s a indicator of the driver crashing and Windows restarting it. And UE seems to be particularly sensitive to any device changes (video or audio) while it’s running.

Edit: And if it is an Nvidia card, skip installing that “Nvidia Experience” trashware on your fresh reinstall.
