I launched the 4.18p1 and then converted my 4.17project（make a copy）,after that the engine would crash when the project was loaded about 90%.The crash both happens on pc and mac.However,I have tried to create a clean new project with 4.18p1,the crash never happens.So the crash may due to certain specific settings in my project.Sadly,I cannot upload my whole project to let you test since it is so large to upload and due to private reasons.But I can provide the log from Windows.Thanks a lot!

Hello ,

I have a couple of other questions to help investigate your issue further.

  1. Can you post the callstack for your issue?
  2. Does this issue happen on your end for a clean 4.17 project that is upgraded to a 4.18 project?
  3. For your project iof you move the startup map out of the project folder and open the project, does it still crash?

Thanks!

1.here’s the call stack file from macos sierra

2.this issue does not happen

3.if i remove the startup map,the editor can successfully load with the default untitled map.maybe there are some blueprints that cause the crash…
