Linux: User is logged out on specific hardware during processing assets for MultiplayerSample project

[LB-ArturZieba]

Describe the bug
On one of the machines (GPC-800, hardinfo file can be found in the Video and hardinfo file section) attempting to process all of the MultiplayerSample assets in Asset Processor results in user being logged out. This occurs at around 1700 - 2000 jobs left and effectively blocks using anything related to MultiplayerSample project (Launchers and Editor). This also occurred on both Source and Pre-built SDK engine configurations.

This issue did not occur on regular projects (Default Template projects with some Gems added) built on this PC.

MultiplayerSample project was built successfully following this instruction: https://github.com/o3de/o3de-multiplayersample/blob/development/README_LINUX.md (specifically Step 1 Option #1 (Recommended) -> Step 2 -> Step 3 Option #1 (Recommended) - Project-centric approach).

It should be noted that on the same machine, on Windows 10, the MultiplayerSample project was built successfully and NewStarbase's level launched Game Mode after all assets were processed in the Asset Processor.

This issue should be considered as Major.

Steps to reproduce

1. Build MultiplayerSample project following this https://github.com/o3de/o3de-multiplayersample/blob/development/README_LINUX.md instruction.
2. Launch the MultiplayerSample Editor and wait for Asset Processor to process all of the assets (Asset Processor can be launched any other way).

Expected behavior
All of the assets are processed.

Actual behavior
User logout occurs during asset processing.

Video and hardinfo file
Please note that logout occurs at the end of the video where it abruptly stops, a black screen is shown, after which a login screen for Ubuntu is displayed. User can login as usual afterwards:
