Hi, I am trying to create and save a new level in Unreal Engine
But crash. What is the problem?
What you’re doing is correct. However the engine crashes like this are usually down to hardware issues or an install issue. You can try doing a repair install on the engine, or possibly uninstall and reinstall.
The other known issue is Unreal doesn’t like it when you have non-ascii characters in your path (i.e A-Z, a-z, 0-9 and so on) so creating a folder called dev on your C drive and moving the project into it may help if you have non ascii characters somewhere in the path.
Other than that, I can’t offer any other solutions.
