[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

It is not fixed. I'm using Unity 2019.4.16f1 on Windows, and every time Unity hub (2.4.2.0) tries to check for updates, the file "LastLayout.dwlt" will become corrupted, no exceptions.

This issue is not fixed in 2020.1.3f1. Clearly, it's been a problem for some time and keeps recurring. Please do not mark these things as resolved if they are not.

unity becomes more a mess with every version...
i'm full dissapointed ... all those bug's on Mac OS X lately...
soon you can only use it when online...
a big mess is Unity3d now...
work in parallel with UE engine... much better now ...
will switch next year completely...in 2020.1.10f the bug still exist... :-(

Seems .8 on Windows helps a bit but it's still there for some.

I fixed this issue by copy and pasting the CurrentLayout-default.dwlt file from my previous project onto the CurrentLayout-default.dwlt file from a new project. Hope this helps!
I'm on 2020.1.6f1

Latest issues
- Shadows are not cast when you first Blit the Shadow map and then set it back to Buffer
- Changes to instanced detail mesh material don't immediately apply
- [uGUI] Vertices retrieved from GetUIVertexStream method cannot be modified when adjusting them through script
- Scroll bar scrolls less in the Package Manager packages than elsewhere when pressing on the empty scroll bar area to scroll
- Undo.RegisterCreatedObjectUndo dirties the scene, but no actual changes to Scene are made
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):
Tested fixed in 2020.1.14f1
Unity no longer creates an infinite loop of popup dialogs when attempting to load an invalid or corrupted layout.
