Reproduction steps:
1. Open the attached project ("GlobalIdBug22.1.0a13.zip")
2. Drag SceneA and SceneB_(To unload) to the Hierarchy window
3. Select GlobalIdBug under SceneA in the Hierarchy window
4. Open the context menu of the Script Component in the Inspector window and click "Get GlobalObjectId"
5. Unload SceneB_(To unload)
6. Select GlobalIdBug under SceneA in the Hierarchy window
7. Open the context menu of the Script Component in the Inspector window and click "Log GlobalObjectId"
8. Observe the Console window

Expected result: "GlobalObjectId is not found" is logged in the Console window
Actual result: "GlobalObjectId is not found" is logged in the Console window and an error is thrown:
Assertion failed on expression: 'manager != NULL'
UnityEditor.GlobalObjectId:GlobalObjectIdentifierToObjectSlow (UnityEditor.GlobalObjectId)

Will this be backported to 2020.3 LTS like the other GlobalObjectId fixes?
