MultiplayerSample SampleBase level is not loading properly when launched via ServerLauncher, and GameLauncher executables

[LB-ArturZieba]

Describe the bug MultiplayerSample SampleBase level is not loading entities containing network components when launched on the MultiplayerSample.ServerLauncher/MultiplayerSample.GameLauncher as a standalone level, or via the host/connect setup. It should be noted that when the Game Mode is started in Editor on the SampleBase level, it works as expected.

Please refer to the attached Game.log and Server.log files attached in the Video, Server.log, and Game.log section.

Prerequisites

1. Clone the MultiplayerSample project to a chosen folder as described on the https://github.com/o3de/o3de-multiplayersample page.
2. In the Project Manager go to New Project... > Add Existing Project, in the Select Project Directory explorer window find and select the cloned o3de-multiplayersample project folder from step 1.
3. Build the MultiplayerSample project in the Project Manager.
4. Launch the MultiplayerSample project, and wait until all assets are processed in the Asset Processor.
5. In the Welcome to O3DE window click Open... and find the SampleBase Level, open it.
6. In the Command Line navigate to the o3de-multiplayersample and build the MultiplayerSample.ServerLauncher executable if not present (Command used during this issue reproduction was: cmake --build build\windows --target MultiplayerSample.ServerLauncher --config profile).
7. Go back to the Editor, verify that the level is loaded properly, and the Game Mode is fully functional.

Steps to reproduce Steps to reproduce the behavior:

1. Make sure all O3DE-related applications are shutdown (e.g. Asset Processor, Editor).
2. Launch the MultiplayerSample.ServerLauncher executable built in the Prerequisites.
3. After the ServerLauncher is loaded, press the tilde key (~), and in the Console execute command loadlevel SampleBase.
4. Without closing the Console execute another command host.
5. Without closing the ServerLauncher window launch the MultiplayerSample.GameLauncher executable.
6. After the GameLauncher is loaded, press the tilde key (~), and in the Console execute command connect.
7. Navigate between both the ServerLauncher, and GameLauncher windows, and attempt some input in the scene itself.

Expected behavior The entities containing network components (boxes and player) are spawned.

Actual behavior No network entities are spawned on neither the ServerLauncher nor the GameLauncher.

Was unable to repro this with the latest stabilization installer with the latest version of MultiplayerSample project, but I'd like to give it another shot with the new release and possibly development, just to be sure.

No longer an issue, main level has also changed to NewStarBase. Closing as stale/DNR

[LB-KacperBieniek]

Confirming the issue has been closed. SampleBase level is no longer a part of MultiplayerSample project.
