Hi Jiri,

  • Does this occur in a clean, blank project with no additional content or is it limited to one project?
  • What steps are you taking to reproduce this on your end?
  • Can you post the crash logs from \Unreal Projects\PROJECTNAME\saved\logs\ closest to the time of the last crash so I can take a look?

Hi Jiri,

We have not heard from you in several days. I am marking this as answered for tracking purposes. If you are still experiencing this error, please comment with the requested information.

Hi,

sorry for the delay i was pretty sick.

Does this occur in a clean, blank project with no additional content or is it limited to one project?
I haven’t test on blank project. Happened on my project only. Didn’t happened again.

What steps are you taking to reproduce this on your end?
I was just switching between two levels in editor. I do not have any 100% repro steps.

Can you post the crash logs from \Unreal Projects\PROJECTNAME\saved\logs\ closest to the time of the last crash so I can take a look?
Unfortunately the logs got overwritten.

Was switching between 2 persistent levels to edit them. Used Control+o.

What method were you using to switch levels. Are they sublevels within the same persistent level or completely autonomous? Were you switching during PIE using a console command or did you switch for editing purposes? If for editing purposes, did you click the map in the content browser or go to file>open level?
