2D projects created with versions from 2023.1.0a25 to 2023.1.0b4 fail to upgrade to 2023.1.0b9 and later 2023.1.0bX versions



How to reproduce:
1. Create a new 2D project
2. Close the project
3. Open the project with 2023.1.0b9 or a newer version

Expected result: The project opens in the selected editor
Actual Result: The project does not open, and the editor gives the following message “No valid user created or default window layout found“

Reproducible with: 2023.1.0a25, 2023.1.0b4
Not reproducible with: 2020.3.47f1, 2021.3.24f1, 2022.2.17f1, 2023.1.0a24, 2023.2.0a12
Fixed in: 2023.1.0b5

Reproducible on: Windows 10, Windows 11

Workaround: Change it to one of the 2022 versions and then upgrade to the desired 2023.1.0bX version

  1. Resolution Note:

    It is fixed in later version of Unity. It seems a change has happened in between versions that made serialization of EditorWindows (which are failing while loading the default layout in this specific case) but it was fixed in a later version.

    Regardless of your age, you can dive into these games without feeling out of place.

    It's possible to create new projects and open them, but every single existing project we have now cannot be opened. I've studied the function LoadLastUsedLayoutForCurrentMode in WindowLayout.cs that creates the dialog, and it seems broken and unable to reset the factory layout. Been in a loop all afternoon and running out of things to try.
