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

Thanks, I got it working only copying over:
Currentlayout.dwlt
CurrentLayout.dwlt

 

VERY EASY FIX
This fix will not damage anything besides your custom layout (which is easy to re-create) and has very little risk, even to a beginner

Cause: Unity can't load window layouts (due to restart or similar) and when you press load default, it works, but then you press quit and it corrupts the default, so it never works.

Solution: Copy the default before pressing quit. After quitting, delete the corrupted default and replace it with the one you copied. This worked multiple times for me.

PROCEDURE ON MAC:
1. In finder, search for currentlayout-default and make sure you are searching under "This Mac", not Recents or anything else
2. Duplicate the file named CurrentLayout-Default (right click => duplicate)
3. Drag the duplicated file to the desktop. Nothing should change in your finder window, but CurrentLayout-Default should show up on your desktop
4. In Finder, select the original currentlayout (not the duplicate) and press Command + Up Arrow (this will find the folder that the file was in, the parent folder)
5. Rename the file on the desktop from "CurrentLayout-Default copy" to "CurrentLayout-Default"
6. Press "Quit", but leave the finder search open
7. In finder, delete CurrentLayout-Default within finder, and drag in the CurrentLayout-Default in the desktop.
8. Re-open Unity
9. Open your windows and place them where you want
10. Save your layout in the top right by pressing layout, and save layout
11. Re-open Unity again to see if it worked, and if it didn't, redo the steps and try not to miss anything

PROCEDURE ON WINDOWS:
Note: I have not tested on windows but the idea is the same as mac
1. In File Explorer, search for currentlayout-default
2. Duplicate the file named CurrentLayout-Default (right click => duplicate)
3. Drag the duplicated file to the desktop. Nothing should change in your File Explorer window, but CurrentLayout-Default should show up on your desktop
4. In File Explorer, select the original currentlayout (not the duplicate) and find the parent folder (look up a tutorial if you need to, not an expert on this on windows, on mac you do Command + Up)
5. Rename the file on the desktop from "CurrentLayout-Default copy" to "CurrentLayout-Default"
6. Press "Quit", but leave the File Explorer search open
7. In File Explorer, delete CurrentLayout-Default within File Explorer, and drag in the CurrentLayout-Default in the desktop.
8. Re-open Unity
9. Open your windows and place them where you want
10. Save your layout in the top right by pressing layout, and save layout
11. Re-open Unity again to see if it worked, and if it didn't, redo the steps and try not to miss anything

I really hope this helps, I was worried when I couldn't open my project. Just make sure to save your layout once you can get back into Unity.

 

Tried this and it works! I also tried the deletion of "C:\Users\%USERNAME%\AppData\Roaming\Unity" (etc) with deactivation and that did nothing. For future reference note that this only happened with a new project, my old project loaded fine.

 

Thanks a lot, this solution works on my Unity 2020.1.4f1

 

This worked (Unity2020.1.5f1) just with the Currentlayout file.

 

I'm having the same problem, sadly I can't open my game anymore, because none of the given options works. Im using 2020.2.0b1

EDIT: Tyson guys! I tried what you said and I could open the game now!

 

Same problem with 2020.1.5f1 with a fresh project. The weird Load Default Then Copy Manually approach worked for me. This is pretty bloody shambolic if we're honest.

 

Hi guys ! I fixed it copying the Default.wlt file and renaming it as CurrentLayout-default.dwlt .
It works like a charm!

 

Amazing, thank you!

 

Hello, I'm new to Unity and have been having trouble getting Unity to start a New project. I'm not sure what to do with the work-arounds you mention. Can you walk me through the process of finding the files to modify?

 

This worked for me in 2020.1.5f1 on the Mac! Thanks!

 

Hi,

The problem persists for Unity 2020.1.6f1. When will there be an update on this problem?

I used Google Translate.

 

THANK YOU!

 

This worked. You can actually see Unity replacing the standard 18kb dwlt file with a 1kb corrupted version, which causes a null reference exception during the editor load.

Incidentally, I was still having this error in 2020.2.0b2.3094.

 

Thanks a lot .That works for me.

 

I did Harryr's second piece of advice and it worked perfectly! Thank you so much!

 

I noticed my issue after bringing a project from home into work, but not sure this was the cause. New and old projects alike would not open. Hyp-X solution did the trick for me.

Both versions were 2020.1.4.

I would note that my region settings seemed to already be 'UK'. The timestamp on the 'CurrentLayout-default.dwlt' is strange - backdates to around 5 weeks prior and a different time. (I created the copy on 28 Sept 2020, 10:05:45, but the modified file was on 21 Aug 2020, 00:47:14). Not sure what that's all about.

 

I'm having the same exact issue, my problem startd yesterday when trying to create a blank new 2D project. I have never had this problem before. I cannot seem to resolve the issue.

 

Rizwan's solution also worked for me. Thanks

 

Work around FIX.
1: Go to a fresh or newer project that is working and go to the library.
2: copy the CurrentLayout-default.dwlt from this fresh/new project.
3: Paste it into the curropted project library folder.

BAM! Works again.

 

For Unity 2020.1.5f1.4487 Personal the previously given solution works for me.

1. Go to Roaming\Unity\Editor-5.x\Preferences\Layouts\default\
2. Delete LastLayout.dwlt
3. Start Unity again

** This resets the positions of the windows. So you have to place them according to your preferences again.

 

I also have the same problem I have the newest version of Unity installed which I think is the newest 2020.1.6 version and I can't even create new projects and whatever I try doesn't fix it.

 

Same.

 

That's working 2020.1.6f1

 

This one works for Unity 2020.1.6f1

 

this solution worked last night, happened again in the morning, So tired of trying all these solution. Anyone?

[running: 2020.1.5f1]

 

To everyone else who got stuck like me, it got fixed with installing new graphic drivers (on Windows)

 

Yes this works for me

thing is you have to do it for every project

 

This worked for me. (2020.1.6f1)

 

Thanks! Worked like a charm. Hopefully, this awful bug gets fixed soon

 

Still an issue in Unity 2020.1.6f NOT RESOLVED - please fix already

The workaround mentioned above did not work for me, I had to copy the CurrentLayout file from an existing project into the newly created project.

 

this worked for me!

 

I tried every other possible work around, and finally this worked.
Confirmed, this works:
Press [Load Default Layout]
2. Unity copies the correct default layout to CurrentLayout-default.dwlt
3. Unity complains that it still cannot load the layout
3a. Press Load Default Layout. < this fixes the file
4. Copy the now correct CurrentLayout-default.dwlt somewhere < copy it from the project that's not working from your project's "Library > CurrentLayout
5. Press Quit
6. Unity corrupts the file during quitting
7. Copy back the correct CurrentLayout-default.dwlt
8. Start Unity again

 

for who doing everything and still not working
change extension on this file from txt to dwlt and copy the file to library
open the project will work

 

That Works for me Thanks, I was stuck not been able to open Unity again... This need to be fixed as it seem that it gets indeed corrupted on quit.

Thanks again for the workaround

 

Happened to me AGAIN this morning.

ProBuilder sus!

How many of you with this issue are using ProBuilder and have the ProBuilder window open?

 

It's been happening to me again and again for some time now, to be honest it makes me puke, there's no point in reinstalling Unity or the whole UnityHub or even a completely new version of unity. This is an extremely massive problem which is spread over several Unity versions and should be already solved..

 

Thank you..

 

I had Same Problem with 2020.1.7f1

I fixed it by Deleting : CurrentLayout-default.dwlt

Note, this was a fresh project, and had this problem on creation, also it was my first attempt to use 2020.1.7f1

 

Hoping this issue is fixed for good after 2020.1.8.

 

Easy fix:
Just kill the unity process tree after you hit the [Load Default Layout] ONCE! Next start will be ok.

 

I don't think it is corrupting on quit. It looks like when you boot the project the update dialog box opens. every time this box is seen I get the bug. When doing the whole delete/replace file after this failure, no box. I've come to this thinking as before I opened unity for the first time today, I replaced the file thinking it was corrupt. still got the bug. Did replace after closing unity, after the bug, and works like this fix always does. Looks like it may be the update window. I could be wrong, not the most familiar with unity, but I just wanted to add more, possibly relevant, data to the discussion.

Hope this puts people on the right track to finding where the bug is originating from.

 

I am having the same problem when creating a project. Please help me. This is for school

 

Just passing through to say that trying to create an URP project still fails with this error. I'll just create a basic 3D one and add URP. Is there some down side to doing this?
Unity 2020.1.0f1
Edit: Whoops... it's not opening the basic 3D project either.

 

Does not work for me. Still can't open any of my Unity projects.

 

Really wondering what the deal is. I can't open Unity whatsoever. None of the listed "fixes" are helpful. Anyone working on this?

 

problem fixed here :

 

confirmed works for 2020.1.f1 Personal license

EDIT: Its worth noting this is necessary for each new project. Tedious.
