Issues when loading RPI/AuxGeom sample

[LB-TomaszSerwanski]

Describe the bug The following issues occur when loading the RPI/AuxGeom sample on a specific platform:

• Windows: Loading the RPI/AuxGeom sample takes over 15 minutes on a mid-range machine. During that time, the Standalone is frozen and unusable.

• Linux: Loading the RPI/AuxGeom sample crashes the AtomSampleViewer.GameLauncher (we were unable to verify on the Standalone due to #392).

Please note that the logs are not generated for the Linux crash.

Prerequisite

• AtomSampleViewer built.

Steps to reproduce Steps to reproduce the behavior:

1. Launch AtomSampleViewerStandalone.exe.
2. Load Samples/RPI/AuxGeom.

Expected behavior The sample loads succesfully.

Actual behavior Windows:

• The Standalone freezes for a very long time (over 15 minutes) before loading the sample.

Linux:

• The GameLauncher crashes.

I'm getting the same bug using stabilization/2205 on both o3de & ASV.

Verified as fixed on both PC and Linux on Stabilization_2205 (fa43be1). RPI/AuxGeom sample loads quickly on both platforms and remains stable.
