Steps to reproduce:

1. Create a new Universal 3D project.
2. Open Window > Search > Scene.
3. Double click on SampleScene. It may take a moment to appear as an option.

Actual results: NullReferenceException appears in the console, but the scene opens. Error detailed below.

Expected results: No error message. 

Reproducible with versions: 6000.0.6f1, 2023.1.0b8, 2023.1.0a15

Not reproducible with versions: 2023.1.0a14, 2022.3.33f1

Can't test: 2021.3.38f1, no Window > Search > Scene option.

Tested on (OS): MacOS, Ubuntu 20.04, Windows 11

Notes:

• Did not repro for me on a new 3D (Built-in RP) project.
• {}Did not repro for me on Windows 11{}, but does repro for me on MacOS and Ubuntu. Mainly tested on MacOS (Intel).
• Full error message:
