Description

I tried 10+ times but am unable to get this to reproduce locally. Licensee reports that this is a rare crash for them.

Steps to Reproduce
  1. Create level with lots of navigation relevant actors including several with NavModifierComponent
  2. Enable async static mesh compilation via Editor Preferences -> General - Experimental
  3. Load map
