“Unsupported type LocalizedString” error appears when modifying a LocalizedString inside a serialized object that’s inside a list which is inside a scriptable object

How to reproduce:
1. Open the user’s attached “repro.zip” project
2. In the Hierarchy, select “BrainControl” GameObject
3. In the Inspector/Debug window, go to “Progression Driver” Component
4. Select any of the elements and press the “-“ button to remove it
5. Observe the result

Expected result: No errors
Actual result: “Unsupported type LocalizedString” error appears

Reproducible with: 2021.3.29f1, 2022.3.7f1, 2023.1.8f1, 2023.2.0b4

Reproduced on: macOS 13.4.1 (Intel)

Notes:
-the issue is also reproducible when instead of the 4th step:
changing any field of the element (ex. “Comparison”)
changing the number of “Quests”
closing “LocalizationDrawer”
applying “Quests” to Prefab
