Yes

NullReferenceException is thrown and unnecessary Re-Binding of ListView Elements when modifying List Elements in custom Inspector with Generic SerializedProperty

--

-

Reproduction steps:
1. Open the attached “BugRepro” project
2. Open the “Assets/Scenes/SampleScene.unity” Scene
3. Click on the "CarSettingsManager" GameObject in the Hierarchy view
4. In the Inspector view, modify any of the fields in the "Car Settings List"
5. Observe the Console window

Expected result: No errors are thrown, and list elements remain bound without unnecessary un-binding and re-binding upon modification
Actual result: “NullReferenceException: Object reference not set to an instance of an object” error is thrown and list elements are unnecessarily un-bound and re-bound with each modification

Reproducible with: 2022.3.28f1, 2022.3.39f1
Not reproducible with: 2022.3.27f1, 6000.0.12f1
Couldn't test with: 2021.3.40f1 (No GUI Implemented)

Reproducible on: Windows 11
Not reproducible on: No other environment tested

    I want to add that the primary issue here is not the NullReferenceException itself, but the unbinding and re-binding of ListView elements unnecessarily on every value change. It is here that the NullReferenceException occurs, but this should not be happening in the first place.
