Steps to reproduce:
1. Open the “Users attached project”
2. Open the “GameStart” Scene
3. Make sure to keep the Systems window closed or hidden
4. Enter Play Mode
5. Press “Continue” through Game View and wait for the _“_HRK_Main” Scene to fully load
6. Clear the Console window
7. Open the Systems window and observe the Console
8. Open the Journaling window

Expected results: No errors are thrown in the Console and the Systems and Journaling windows *show data*
Actual results: NullReferenceException Error is thrown and the Systems and Journaling windows *show no data*

Reproducible with versions: 1.2.3 (2022.3.46f1)

Reproducible on: Windows 11
Not reproducible on: no other environment tested

Notes:
- The exception always occurs in the same place when populating the world proxy, regardless of where the call is invoked. The NullReferenceException comes from a null system handle to an unmanaged system in the Content world.
