Regression
Yes
Crash on IsTypeTreePPtr when switching variable to another type that inherits from the same class
Reproduction steps:
1. Open the user's attached project
2. Open the scene 'Assets\Scenes\SampleScene'
3. Select 'TestObject' in the Hierarchy
4. Tap the 'Change Type' checkbox in the Inspector
Expected result: The Editor does not crash
Actual result: The Editor crashes
Reproducible with: 2021.2.0a18, 2021.2.0b13, 2022.1.0a10
Not reproducible with: 2020.3.19f1, 2021.1.23f1, 2021.2.0a17
Couldn't test with: 2019.4.30f1
Notes:
1. The 'Change Type' checkbox may have to be pressed multiple times to reproduce the crash.
2. In the versions that do not reproduce the crash an error is thrown instead:
"Fields with [SerializeReference] cannot serialize inflated generic type in this case: TestScript.D<System.Int32>".
The same error is in the logs right before crashing in the versions that reproduce the issue.
