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

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".

I'm experiencing the same problem on Windows (2020.2.0a21 and 2020.2.0b1). However, I have been unable to find a workaround. Deleting LastLayout.dwlt and reverting to factory default settings did not help.
From Editor.log:
[MODES] Loading mode Default (0) for mode-current-id-Dummy
[LAYOUT] About to load Library/CurrentLayout-default.dwlt, keepMainWindow=False
Failed to load window layout: System.NullReferenceException: Object reference not set to an instance of an object

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.
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.
Resolution Note (fix version 2020.1):
