Error in the Console when generating a PropertyBag for a Type that derives from a partial type with a private member

How to reproduce:
1. Open the attached “PropertyBagBug.zip“ project

Expected result: No errors in the Console
Actual result: “error CS0122: 'BaseClass._somePrivateField' is inaccessible due to its protection level“ errors in the Console

Reproducible with: 2022.3.20f1, 2023.2.11f1, 2023.3.0b8
Couldn't test with: 2021.3.35f1 (Different errors in the Console)

Reproducible on: macOS 14.2.1 Sonoma (Intel)
Not reproducible on: No other environment tested

Notes:

• The issue reproduces when a property bag is generated for a type that derives from any partial type with a member that has “[CreateProperty]” or “[SerializeField]” and is not directly accessible from the derived type (private)
• The issue also reproduces if the “_somePrivateField” variable is “protected” or “private protected” in the “BugExample“ Script
