Editor crashes when adding a button to a UMG widget

Create a new UMG widget, drag and drop a button editor crashes.

If you drag a button onto the hierarchy it doesn’t crash but if you click on the button in the designer it crashes as well.

Master branch last commit: 9abb4575d646e95dae3803b28ce488c376c7761a
Crashes in promoted branch as well
