Description

Selecting a Camera Component in the Sequencer window when the level is locked causes the Engine to crash. 

This was reported and tested in 4.20.1 (CL-4233996). This was reproduced in 4.19.2 (CL-4033788) and Main 4.21 (Cl-4280116)

Steps to Reproduce
  1. Open the UE4 Editor and create a blank project
  2. Add a Cine Camera Actor and a Level Sequence to the Level
  3. In the Level Sequence add a Camera Cut Track and add the Cine Camera Actor to it
  4. From the Cine Camera Actor add a Camera Component
  5. Right Click on the Cine Camera Actor and select "Convert to Spawnable"
  6. Back in the Viewport lock the Level in the Levels window
  7. Click on the Camera Component in the Sequence window

Results: The Editor crashes

Expected: The Camera Component is selected
