Resolved Can not Launch Unity Due to "Failed to load window layout"

This worked for me.

 

This is definitely a problem, seeing as how every time I create a new project I have to go in and delete these files. There needs to be a more permanent fix.

 

For me it was because I had com.unity.ui@1.0.0-preview14 installed with non default font selected (Verdana).

Had to

1. Uninstall com.unity.ui packages in "\Packages\manifest.json" and "\Packages\packages-lock.json"
2. Open editor ignore compilation errors
3. Change font to default
4. Reopen editor
5. Install com.unity.ui package again

Hope this helps someone!

 

Still having that issue on 2019.4.12f1
Deleting

CurrentLayout.dwlt

fixed it for me

 

I can confirm that in 2020.2.1f1 this issue is still around. I was able to navigate through it by doing the thing where I copy Library/CurrentLayout-default.dwlt somewhere and then quit the editor (it then corrupts the file somehow) and then copied it back into Library/CurrentLayout-default.dwlt while the editor is closed. When I re-open the editor everything works fine.

This is an absolute nightmare considering that unity already takes far longer than expected to import from scratch and build the library... even after I finally was able to open the editor it just resumed importing assets. I hopped on my machine to make a few simple changes tonight and the editor itself completely blew away my opportunity. I got nothing done tonight and I am pretty bent out of shape over it.

 

I had a bunch of people trying to open my project in Unity 2020.1.6f1 who experienced this issue afterwards. Solution was to delete the UserSettings folder which probably included a custom window layout I had.

 

Here's what is working for me... Was ready to chuck the cpu in thah river...

I go into the library folder of any working/loading project
I copy the file CurrentLayout-default.dwlt
I paste the file into the Library folder of the bum project.
Now the project loads good.

Seems to work for me... Mac 10.13.6 Unity 2020.1.5f1
I now am just keeping a folder with the CurrentLayout-default.dwlt file in my Unity Projects folder so I can copy paste and actually get to work rather than fight this issue...

 

We resolved this case by copying two files at Library from working unity project into the current Library directory.
CurrentLayout-default.dwlt and CurrentMaximizeLayout.dwlt

 

You Legend!

 

Thanks mate, I can confirm that this worked for me

 

Just close The Scene and Open it again

 

closing the scene does not always work, I found out the problem for me was I had saved my layout to a file, and on newer versions of unity it fails just clear this and you might find when you create a new project it works?

 

The only thing that helped me was:
1. Open "Help" --> "Check for updates" in the editor menu bar
2. Deactivate the checkbox "Check for Updates"

 

I deleted CurrentLayout.dwlt from Library Folder. Created a new Unity project ,copied and replaced the CurrentLayout-default.dwlt
