Unreal Editor spammed with error 16

[bbuckley94]

Summary: When the RenderStream plugin is added to a project, the output log is spammed with the following error when the Editor is launched:

[2021.12.22-09.07.07:879][115]LogRenderStream: Error: Error awaiting frame data error 16
[2021.12.22-09.07.07:895][116]LogRenderStream: Error: Workload asset not created
RenderStream Callstack:  < rs_awaitFrameData < RSAwaitFrameData

With the current retail version of d3 and UE plugin, the callstack is blank. When testing with the tip of r20.3 and r1.28_UE4.27 the callstack information is included.

Bug reduction:

• Seen in r20.0.3 (84705) with RS1.28 (UE 4.27) v2 - latest public release.
• Seen in r20.3 (84847) with RenderStream-UE_r1.28_UE4.27_r1.28_UE4.27_r20.0_v2-3-g4eb863a (Patches Applied).

Steps to reproduce:

1. Launch UE and create a new blank project
2. Add the plugin to the project folder as normal
3. Restart UE
4. Open the output log (notice error spam)

This is assuming we are only encountering the issue when running outside of a workload, if it also happens in a workload please make a new issue as it will not be happening for the same reason.
