I had this issue when I first updated to 4.10 and it’s still happening in 4.10.1 the only workaround is to reset layout in the windows toolbar and live with all toolbars etc. open

Replication Instructions:

  1. Create a widget blueprint and open it
  2. close the animation and
    timeline toolbars at the bottom
  3. goto windows → save layout
  4. Close the widget and then immediately Open the widget
  5. Instant Crash

The only dump deataisl I get is ntohing
