How to reproduce:

1. Open the project “IN-89805_LocalizationProblem”
2. In the Hierarchy, click on the “GameManager” GameObject
3. In the Inspector, expand the “Script Including Localization (Script)”
4. Observe the Inspector

Expected result: The Inspector expands the script file with the fields listed
Actual result: The script is not expanded, and no fields are visible

Reproducible with: 2022.1.0a5, 2022.3.55f1, 6000.0.36f1, 6000.1.0b4, 6000.2.0a1
Not reproducible with: 2021.3.48f1

Could not test with: 2022.1.0a1, 2022.1.0a4 (Errors related to the Localization and Addressables package dependencies)

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

Notes:

* The {{IntVariable}} seems to be not serializable. Hence the {{public}} or {{[SerializableField]}} attributes cause problems when used with the {{.IntVariable}} class
