How to reproduce:
1. Open the attached “serializable_autoproperties_issue” project
2. In the toolbar, navigate to the “Repro > Serialization issue” window
3. Press the “Reload assemblies” button
4. Observe how some of the values are assigned null values until the window is reopened

Expected result: Variables are assigned the same values after script assemblies are reloaded
Actual result: Variables with certain properties are not initialized properly, and are not assigned their respective values

Reproducible in: 2021.3.31f1, 2022.3.13f1, 2023.1.20f1, 2023.2.1f1, 2023.3.0a15

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

Note: As a workaround, introducing an empty default constructor in the script, i.e “public SerializableData() {}” is enough to prevent the issue from reproducing
