Can you provide a crash report? If there is none, what OS are you using? If you're using Windows 11, UE4 games aren't 100% supported on that OS yet as far as I'm aware and are prone to crashing.
Maybe some Windows 11 PCs don't run into that issue? Tbh I'm not 100% sure, it's just something I read online a few months back with UE4 games crashing often on Windows 11 PCs, but it may just be the game simply crashing on your PC for some unknown reason.
