Editor crashes when trying to create a new blueprint class

The editor crashes when I try and create a new blueprint class in 4.13 on a mac.

Hi Void Goat,

I’ll need more information in order to help you with this issue…

  1. Can this issue be reproduced in a blank, Blueprint, Third Person Template project?
  2. Is this problem occurring in a project that is being upgraded to UE4.13 from a previous version?
  3. Are you in the Launcher (Binary) Version or Github Version?

Let me know the above and we will continue to investigate.

Thanks,

.

Hi,
In new blank projects I can open the “Choose are Parent Class” window, but if I try to expand it to see all classes then it crashes. In projects migrated from 4.12 it crashes immediately on trying to create a new class.
I am using the Launcher version.
Thanks!

Hi VoidGoat,

If you want to upgrade a project from a previous version of the Engine, make sure you Launch the newer version of the engine and select “Make a copy of the Project…” This will keep a working version of your project in the event the changes in the new version of the engine creates a conflict with the old version. (The recommended workflow is to stay in the version you started in unless you need a fix in a newer version.)

That said, there are some things you can try to correct your problem. If you are using the Launcher/Binary version of the Editor, navigate to the Library and select the yellow down arrow for UE4.13. Select “Verify.”

If this does nor resolve the issue, Navigate to the DerivedDataCache folder in the install directory and delete the contents before restarting the Editor.

If you are building this from Source using Github, you will need to rebuild the Engine using XCode.

Let me know if this does not resolve the issue.

Thanks,
