Description

The editor crashes when you Force Delete the vertex painted asset in the viewport from the content browser.

This was not a feature in 4.15 therefore not a regression

This also happens in 4.17 - found in Dev-AnimPhys

Steps to Reproduce
  1. Open QAGame
  2. Find SK_Mannequin and duplicate the Skeletal Mesh
  3. Add the duplicated SK_Mannequin to the viewport
  4. Change to Paint Mode and select the SK_Mannequin in the viewport
  5. In the content Browser - select the SK_Mannequin duplicate and delete > Force Delete

Result: The editor crashes
