Full title: Crash on ModuleMetadataBindings::GetModuleIncludeSettingForObject when Removing/Adding SerializeField from script attached to Prefab that is shown in Inspector

Reproduction steps:
1. Open the user's attached project
2. Focus the Prefabs/Player prefab in the Inspector
3. Click on "Edit Script" in the "Player_Setup" component
4. Add the following lines to line 9 in the "Player_Setup" script:
[SerializeField]
float testFloat = 5f;
5. Save the script, then click on "Player" prefab in the Editor to go back into the editor with the prefab still open in the Inspector

Expected result: Script compiles and Editor is focused
Actual result: Script compiles and Editor crashes
