Launching UE workload with RenderDoc plugin enabled crashes on startup

[eclazi]

1. Create UE project
2. Enable RenderDoc plugin - https://docs.unrealengine.com/en-US/TestingAndOptimization/PerformanceAndProfiling/RenderDoc/index.html
3. Run workload when it is launched via d3.
4. Crashes on startup.

Running workload manually with -game works fine. Same issue happens when workload is launched via RenderDoc or nSight with the command line parameters d3 launches unreal with.

@josh-disguise has managed to run it under nSight, so may have thoughts.

Managed to run with nSight Systems by patching the engine definition in d3 to launch with the command line launcher, but I've had the same experience with nSight Graphics. Crash is somewhere inside Unreal's dx12 support.
