Window Layout.cs:40 error (Ubuntu)

Hey there,
New to this program. I just recently download Unity. I have tried the version 2019.4.13f1 and 2020.1.11f1.
I have tried uninstalling it and reinstalling it. I have also tried installing the .deb files.
I am using Ubuntu 20.04.1 LTS. I have checked all software updates and graphics card updates.

The error always appears if i use an existing project or a brand new project. It still comes up.
After about 5 minutes. If I load up any type of menu. The menu's are are black. If I close down unity and reload it. It works for another 5 minutes. I am hoping there is a fix for this instead of having to constantly close it and reopen it.

This is the only error I am getting on it.
The editor layout could not be fully loaded, this can happen when the layout contains EditorWindows not available in this project
UnityEditor.WindowLayout:LoadDefaultWindowPreferences() (at /home/bokken/buildslave/unity/build/Editor/Mono/GUI/WindowLayout.cs:40)

I have tried changing the layout setting under Window and reverting to default setting.
Much help appreciated. Thanks!

 

Any thoughts on this?
