Regression

Yes

Crash on UnityEditor.AssetDatabase:OpenAsset because assertion fails on prefabInstance.GetRootGameObject().IsValid() expression while opening a specific Scene

--

-

Reproduction steps:
1. Open the attached "crash_IN-69862" project
2. Open the "3" Scene
3. Observe the crash

Reproduced with: 2022.2.0a13, 2022.3.21f1, 2023.2.13f1, 2023.3.0b3
Not reproduced with: 2021.3.37f1, 2022.2.0a12, 2023.3.0b11
Fixed in: 2023.3.0b4

Reproduced on: Windows 10 (22H2)
Not reproduced on: No other environments tested

Notes:
* The crash is produced by the "\Assets\=== ASSETS ===\Dark_Fantasy\Assets\Prefabs_Grp\BASIC\Floor\Floor_x4_Lod0.prefab"
* The “3“ Scene opens without a crash if the "\Assets\=== ASSETS ===\Dark_Fantasy\Assets\Prefabs_Grp\BASIC\Floor\” folder is empty
* For quite some time I was able to reproduce the crash by having the "\Assets\=== ASSETS ===\Dark_Fantasy\Assets\Prefabs_Grp\BASIC\Floor\” folder empty, opening the “3“ Scene and then importing the “Floor_x4_Lod0.prefab“ into the “\Floor\“ folder. However, crash suddenly became non-reproducible by following this method
* The crash can be sometimes reproduced by importing the "Floor_x4_Lod0.prefab" into the "\Floor\" folder before entering the "3" Scene
* Moving the "Floor_x4_Lod0.prefab" out of the "\Floor" folder and then entering the "3" Scene doesn't reproduce the crash

  1. Resolution Note:

    This was resolved in 2022.3.25f1.
