[BUG] Create UserWidget Widget crashes Editor when PIE
I created a project based on the Blueprint First Person template.
I was experimenting with UMG Widgets, and wanted to not have any widgets added to screen but not remove my Blueprint nodes to create a Widget. I did this by setting the Class variable in a Create UserWidget Widget node to "User Widget". When this is set, the Editor crashes when trying to Play In Editor.
I believe the key portion of the error message in the Crash Reporter is: "Class which was marked abstract was trying to be loaded. It will be null"
This error is repeatable. It will crash the Editor everytime you Play, or Simulate.
This is the callstack from the crash reporter:
Access violation - code c0000005 (first/second chance not available)
