VS Code python extension recently started complaining about a Path error on Win10

Question

When I start Visual Studio Code with a python file I started getting the following error

The environment variable 'Path' seems to have 
some paths containing characters (';', '"' or ';;'). 
The existence of such characters are known to have 
caused the Python extension to not load. If the 
extension fails to load please modify your paths to 
remove these characters.

I checked my path and I did indeed have a ;; appearing. I removed it but, I'm still getting the error.

Here is my current path.

PATH=C:\ProgramData\Oracle\Java\javapath;C:\Program Files (x86)\Intel\iCLS Client\;C:\Program Files\Intel\iCLS Client\;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files (x86)\Common Files\Lenovo;C:\SWTOOLS\ReadyApps;C:\Program Files\Calibre2\;c:\Program Files (x86)\Microsoft SQL Server\100\Tools\Binn\;c:\Program Files (x86)\Microsoft SQL Server\100\DTS\Binn\;C:\Program Files (x86)\Skype\Phone\;C:\Program Files\IDM Computer Solutions\UltraEdit;C:\Users\Dave\.dnx\bin;C:\Program Files\Microsoft DNX\Dnvm\;C:\Program Files\Git\cmd;C:\WINDOWS\System32\OpenSSH\;C:\Program Files\Intel\WiFi\bin\;C:\Program Files\Common Files\Intel\WirelessCommon\;C:\Program Files (x86)\Sophos\Sophos SSL VPN Client\bin;C:\Users\Dave\AppData\Local\atom\bin;C:\Users\Dave\AppData\Local\Microsoft\WindowsApps;C:\sqlite;C:\Python36\Scripts;C:\Program Files\Microsoft VS Code\bin;C:\Python36;

For me it was just a \ in the end of the Python path:

C:\Users\ME\AppData\Local\Programs\Python\Python37\Scripts\

The moment I removed the last \ the warning went off !
