Description

If you duplicate an asset in the Content Browser before the renaming box prompts input it will cause the Editor to crash.

This was reported and tested in 4.20.3 (CL-4369336). This is reproducible in 4.19.2 (CL-4033788) and Main 4.21 (CL-4399560)

Steps to Reproduce
  1. Open the UE4 Editor and either create a new project or load up an existing one
  2. Select the icon of an asset in the Content Browser
  3. Click at the name of the asset and then fast (before the name will change to the input for rename) right click at the icon of the asset
  4. Choose "Duplicate" from the context menu

Results: It will create a copy of the asset and then it crash.

Expected: Should not crash
