Crash on ModuleMetadata_CUSTOM_GetModuleIncludeSettingForObject when redrawing a serialized property on a Prefab in Inspector

Scene Management


Reproduction steps:
1. Open the attached project ("")
2. Open "CrashScript.cs"
3. Select "CrashPrefab" in Assets so that its properties would be shown in the Inspector Window
4. In "CrashScript.cs" comment/uncomment "public" access modifier before "anyVariable"
5. Click on "CrashPrefab" once again to initiate recompilation and redraw Inspector Window

Reproducible with: 2020.2.0a17, 2020.2.0a20, 2020.2.5f1
Not reproducible with: 2018.4.26f1, 2019.4.7f1, 2020.1.1f1, 2020.2.0a16

First lines of the stacktrace:
0x00007ff68b357295 (Unity) ModuleMetadata_CUSTOM_GetModuleIncludeSettingForObject
0x000001fde73b5e77 (Mono JIT Code) (wrapper managed-to-native) UnityEditor.ModuleMetadata:GetModuleIncludeSettingForObject (UnityEngine.Object)

- Doesn't reproduce on a GameObject
- Doesn't reproduce on any redraw, seems like it has to add or remove a serialized property. For example if a Debug.Log line would be included somewhere in the script, it would have no issue redrawing the Inspector Window
- Reproducible on Windows, OSX

    I'm having this quite regularly (couple of times per day)

    I am able to reproduce it when renaming a serlialized property which is used on a prefab which has some variants (not sure if this is relevant)

    It only occurs when the inspector has the prefab opened, it does not happen when the inspector does not have the prefab opened.
