Cancelling this 2023.2 tech release issue since the support for this release has come to end of life. Cancelling this 2023.2 port case does not affect any LTS or Unity 6 Beta/Preview that remain open.

Reproduction steps:
1. Open the attached “BugRepro” project
2. Open the “Assets/Scenes/SampleScene“ Scene
3. Enter Play mode and observe the value of the “Assets/MyAsset.asset” in the Console
4. Exit Play mode and overwrite “Assets/MyAssets.asset“ (Tools > My Asset Editor > Save My Asset)
5. Enter Play Mode and observe the value of the “Assets/MyAsset.asset” in the Console

Expected result: In both steps 3 and 5, the value logged in the Console is the same
Actual result: In step 5 after the asset is overwritten, it throws NullReferenceException

Reproducible with: 2021.3.33f1, 2022.3.16f1, 2023.2.4f1, 2023.3.0a19

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

Note: Restarting the Editor or reimporting the “SampleScene“ Scene fixes the issue
