Description

Adding a variable of Post Process Settings structure to a blueprint causes the editor to crash when the blueprint is compiled.

Regression:
Yes - Editor did not crash on compile in 4.17.2 (CL 3658906)

Steps to Reproduce
  1. Open UE4 Editor (Any project)
  2. Add blueprint based on actor (ActorBP)
  3. Add variable based on Post Process Settings
  4. Place get node of the variable in the event graph
  5. Compile blueprint

Result:
Editor crashes immediately on compile

Expected:
Post Process Settings node can be used in blueprints
