Description

Editor crashes on blueprint open when shortcut key is implemented through code inside of the BaseEditorPerProjectUserSettings.ini. Code used in repro is directly from Jeff W suggestion in the forum post.

Adding JIRA ticket per Michael N on forum post:

User Description:

Repro Steps 4.14 & 4-10 :

1. In BaseEditorPerProjectUserSettings.ini add this line to the section: [BlueprintSpawnNodes]

+Node=(Class=K2Node_Knot Key=R Shift=false Ctrl=false Alt=false)
2. Clumsy edits may also cause crashing. i.e. Edit the following line in section: [MeshPaintEdit]

DefaultBrushRadi us=128

Steps to Reproduce
  1. Navigate to your engine versions "Engine\Config\BaseEditorPerProjectUserSettings.ini" > open the file
  2. Add "[BlueprintSpawnNodes]
    +Node=(Class=KismetSystemLibrary:PrintString Key=P Shift=false Ctrl=false Alt=false)" without the quotations > Save the file
  3. Open the engine > Create a new Blank project
  4. In the Content Browswer > Create a blueprint actor
  5. Double-click the blueprint to open it

Results: The editor will crash

Expected: For the blueprint to open and have access to the shortcut key that was added (in this case, pressing the P-key should add a Print String to the Event Graph)
