Unreal Engine Issues and Bug Tracker (UE-40938)

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

Run QAGame by running the following command in /Engine/Binaries/Win64/
- UE4Editor QAGame -game -onethread -log
Enter the command: "Open TM-ShaderModels"

Result:
Observe a crash as the map loads in
