Regression

Yes

[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

Note:
- 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

Workaround:
- 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):

    I managed to solve the window layout issue this way:
    - I clicked on 'Load default layout' - the contents of CurrentLayout-default.dwlt reverted to the correct form that would work.
    - I opened the file in Notepad++.
    - It then returned to an empty (corrupt) layout file when clicking 'Quit'.
    - Notepad++ now offered me to refresh the file, which I declined.
    - I now saved the previous, correct file.

    The project now opens.

    I am currently having this same issue... I have tried all suggestions on this page and still nothing. I am unable to load a previous working version of any project nor am I able to create a new project. Any help with this would be greatly appreciated

    Another workaround:

    Copy one of the layouts from the default list in the editor directory into the Library folder overwriting CurrentLayout-default.dwlt.

    i.e.

    C:\Program Files\Unity\Hub\Editor\<Version>\Editor\Data\Resources\Layouts\2 by 3.wlt => …\Library\CurrentLayout-default.dwlt.

    I found a work around, kind of sucks but I removed all installs of the HUB and Unity, cleaned the registry of any "unity" entries and then removed all Unity folders from the Users/.../AppData.

    But now I can open a new project without issue..

    I just starting getting this today, I was using my projects in Unity 2020.1.5f1 without issue, this just today 9/14/2020 after 12PM Est. suddenly I started getting this issue. On all existing projects and creating new projects. I UN-installed all unity versions, including the HUB, did a clean install but I still get same error on a new project.. No matter what I try, from different solutions online, I cannot open a project. This is a serious issue as I am in the middle of my project development.

    I was finally able to open unity by replacing the contents of "Library\CurrentLayout-default.dwlt" (inside the project folder) with the contents of "AppData\Roaming\Unity\Editor-5.x\Preferences\Layouts\default\Default.wlt".
