Hi there!

It can be scene saving, settings saving or else.
I also tryd save by “File” menu.
Graphics RHI: Vulkan.

Very important notice:
Crashes happend ONLY on Vulkan RHI.
I changed RHI to OpenGL4 and no any problems for now.
If someone have same problem and using Vulkan RHI → change it to OpenGL(-openGLv in start command line, where v is version).
You should provide the crash log. It is available in the project directory /Saved/Logs . Helps pinpointing the actual issue.
On unrelated note. I had issues even running the engine using Vulkan on certain graphics cards(Quadro in my case) so fall back to OpenGL is a valid workaround. I have not tested if it affect patched game as well yet but will do so soon.
Sadly that is not the crash log. I know it says CrashDebugHelper at the end but this is not from the run where the engine crashed.
Yeah, i know what log a needed to u. But i askd me "/Saved/Logs/
