Editor error after update

So I just updated to 2018.3.0f2, and the only error I get is:

NullReferenceException: Object reference not set to an instance of an object

UnityEditor.ConsoleWindow.MakeSureConsoleAlwaysOnlyOne () (at C:/buildslave/unity/build/Editor/Mono/ConsoleWindow.cs:312)

UnityEditor.ConsoleWindow.OnEnable () (at C:/buildslave/unity/build/Editor/Mono/ConsoleWindow.cs:294)

UnityEditorInternal.InternalEditorUtility:LoadSerializedFileAndForget(String)

UnityEditor.WindowLayout:LoadWindowLayout(String, Boolean)

When I double click it, no GameObject is selected.
There is no C:/buildslave folder.
Restarting Unity doesn't remove it.
The game still builds fine, but I want to get rid of it. Any ideas?

 

I cant even get the settings to my Target Signal to appear. I downloaded on both my Mac and Windows and I am receiving the same errors.

 

Im having the same issue. Pops up a few times time every time i swap back to the editor or after a few seconds

 

I solved it today by changing the Editor Layout to default, and then customizing it again. Apparently there was a second Console Window hidden somewhere.

 

MakeSureConsoleAlwaysOnlyOne: Make sure there is only one Console Window.

 

This fixed it for me, too.

 

Previous versions of Flyingworm's Editor Console Pro may also cause this issue, so upgrading Editor Console Pro asset is another possible solution.

(This issue was pointed out in this other Unity thread)

Version 3.956 (released Mar 4, 2019)



Added log file mode, allowing you to parse Editor.log

Added search CPAPI command to set the search text field

Fix for Unity exceptions some people are getting in a few Unity versions

Disabling override status bar for now, hack no longer works well with new Unity versions

 

Resetting editor layout to default in the top right fixed it for me too. Thanks Caliber!

 

Hi guys,

This happened to me and then I realized I had TWO Console Tabs open in the editor, you may have one or more, close until you have ONLY ONE CONSOLE TAB.

Hope it helps!

Best of luck to you all!

 

Thanks, guys. Resetting the editor layout worked for me too.

I have this error, and I am using (2020.3). Does anyone know how to solve this issue?
i appreciate if anyone know the solution :S

NullReferenceException: Object reference not set to an instance of an object
