Since v4.23, if you run an Editor Widget, close it, and try to open another map, the editor will crash. This didn’t happen in v4.22.
Here you are a short but clear video: Dropbox - UE4_crash_widget_editor.mp4 - Simplify your life
Or if you are an UE4 user, please, could you confirm it?
Thank you very much and best regards.
