[SerializeReference] Crash when deleting first child element in list
Reproduction steps:
1. Open the attached project "1191858" and "test" scene
2. In the Project window, open "Test.cs", comment out line 44, save it and compile the code by going back to the Editor
3. Uncomment the same line, save it and recompile again
4. In the Hierarchy, select Main Camera object and in the Test (Script) component, expand list P
5. Right-click on the first element in list P (Element 0) and press "Delete Array Element"
Reproducible with: 2019.3.0a2, 2019.3.0b7, 2020.1.0a9
Could not test with: 2017.4.33f1, 2018.4.11f1, 2019.2.10f1, 2019.3.0a1 (SerializeReference inaccessible due to its protection level)
Note1: Crash only occurs when deleting the first element of the list
Note2: If code is not recompiled (steps 2 and 3 are skipped) a silent crash occurs
Workaround: Deleting the SerializeReference attribute stops the crashes
