Frequent crashes on a regular basis

Hello dear helping hands,

I’m now working on several projects with Unreal 4.19.2 (Under Windows 7, 8 GB Ram, 4 GB NVidia Graphics), but I encounter so many crashes (sometimes directly after starting the program), and I can neither pack games nor render movies nor work on my project without crashes and so on. After my latest crash, those are the report files.
Is anyone here able to tell me, what I can do to prevent the Engine from crashing? Any help is very much appreciated :wink:
btw: I don’t have any plugIns, very few blueprints (just the ones that are delivered with the Engine)

“Device remove” means you GPU driver is crashing, try get new drivers. If this still continues this could either a OS problem or some software messing up or hardware issue. Do you have same issuess in games maybe?
