Crash when opening TM-ShaderModels with -onethread

Description

An assert fails when opening the TM-ShaderModels map in QAGame with the -onethread argument. The crash does not occur on any other maps tested. Two other ensure occur before the assert, those issues are being tracked with [Link Removed]

Steps to Reproduce
  1. Run QAGame by running the following command in /Engine/Binaries/Win64/
    • UE4Editor QAGame -game -onethread -log
  2. Enter the command: "Open TM-ShaderModels"

Result:
Observe a crash as the map loads in
