Crash on __pthread_kill when deserializing a different type field with the same name
Reproduction steps:
1. Open the user's attached project
2. Enter play mode, then exit play mode
3. Comment-out line 6 in Data.cs
4. Uncomment line 7 in Data.cs
5. Enter play mode
Expected result: Editor throws an error, that the serialized variable field type has changed
Actual result: Editor crashes

Resolution Note (2022.1.X):
Unity does not support loading existing assets after changing the type of a field from an array to a single element. Doing specific checks for that case to avoid the crash would slow down the loading path for all data because it is not a quick check to perform. We will keep tracking this scenario internally as something to address in our upcoming feature and quality work in the area of data migration support.
