Sagemaker error on "Open Launcher" butto

Simply using the Home/Launcher button called "Open Launcher" or the Launcher "Create notebook" button throws an error trying the open the jupyte r notebook.

But there is nothing wrong the the Sagemaker Domain or User profile because using the button: File > New > notebook it does work just fine.

When using the "Open Launcher" button, AWS CloudWatch logs for the "JupyterServer/default" says:
