[window layout] cannot load editor layout, stuck in infinite loop of "failed to load window layout"

Window management


steps to repro:
1a. copy the attached "corrupted" LastLayout.dwlt into ~/Library/Preferences/Unity/Editor-5.x/Layouts/default/ (or win/linux equivalent directory)
1b. create a new project via Unity hub

Expected: project is created and opens (and... revert factory settings / load default layout buttons fix the issue and Unity opens)
Actual: project is created but then a dialog appears and user is stuck in infinite loop that can only be stopped by selecting "quit"

repro: 2020.2.0a21, 2020.1.5f1
no repro: 2019.4.6f1

- found on MacOS
- "Failed to load window layout" window causes user to be caught in an infinite loop since nothing fixes the issue so the window will stay
- 2019.4.6f1 can successfully open with the "corrupted" LastLayout.dwlt but does show console errors

- try moving or deleting the files at
- ~/Library/Preferences/Unity/Editor-5.x/Layouts/default/LastLayout.dwlt (or equivalent path)
- <PROJECT>/Library/CurrentLayout-default.dwlt

  1. Resolution Note (fix version 2021.1):

    You can resolve this issue by upgrading to the appropriate fixed version:
    - 2021.1.0a5
    - 2020.2.0b12
    - 2020.1.14f1

    What has changed?
    - “Failed to load window layout” popup dialog now displays the error that occurred when loading the layout.
    - Choosing “quit” will remove the broken layout from the cache.
    - Choosing “Load default layout” or “revert factory settings” no longer results in an infinite loop with “Failed to load window layout”
- A console error will indicate why Unity failed to load the window layout - this can be cleared.

  2. Resolution Note (fix version 2020.2):

    Tested fixed in 2020.2.0b12

    Unity no longer creates an infinite loop of popup dialogs when attempting to load an invalid or corrupted layout.

  3. Resolution Note (fix version 2020.1):

    Tested fixed in 2020.1.14f1

    My student is getting this on 2022 and on the Unity 6 preview, even when creating a brand new project, and even after deleting all Unity folders from AppData in order to reset settings.

    Happens with Unity 2022.3.10f1 and 2022.3.11f1. Happened to me after a failed Android build. And I am getting the infinite loop.

    Something is seriously wrong with Unity's pipeline if other people get this too on LATER versions of Unity.

    Confirmed. I'm still having this problem. It's very frustrating to lose my layout, and even more frustrating to find that the issue was marked resolved. How do we get attention back to this issue?
