Unreal engine crashing

Hi, when I try to use Unreal Engine (making a game), after about 5-10 minutes it always crashes, no matter what I’m doing. Because of this, I can’t really do anything in UE. I contacted support, but said they couldn’t help. How can I possibly fix this?!

What’s your specs? You got to provide detailed other than saying the engine is crashing.

Pretty good specs. Do you have any driver updates? Also when does the crash start does it happen every time you make or open a new project?

I checked and I don’t think I have any driver updates, the crash happens when I’m doing something in the project. It doesn’t matter if it’s a new project or an old.

Has it always been crashing or did it just start? Also did you recently update the engine version?

I’ve used it like a year ago and it was working fine, but as soon as I reinstalled it this year, it just starts crashing. I’m using the latest version.

mine crashes randomly also. it’s random and every 5-20 minutes it crashes every time no matter what.

Did you import a heightmap?

I found that if I import a heightmap, the engine crashes randomly. If I do not import a heightmap, I can work without crashing. This is quite frustrating.
