EINVAL error

I downloaded node.js (McAfee squawked but not sure if it is related) and tried to create a grandstack project. I has some difficulty last week and may have done something to my environment variables. The current PATH from the command line looks like this:

C:\Users\jogor>PATH
PATH=C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0;C:\Windows\System32\OpenSSH;C:\Program Files\nodejs;C:\Users\jogor\AppData\Local\Microsoft\WindowsApps;

When I type in this...
C:\Users\jogor>npx create-grandstack-app bgtest

... I get this error:
Error: EINVAL: invalid argument, mkdir 'C:\Users\jogor'C:\Users\User\AppData\Roaming\npm''

On a scale of 1 to 10 where 10 is 'technical rock star' I am about 4.

Help? I really want to learn this neo4j stack.

Thanks.

Not sure which windows version you're running but that's more a node.js / npm issue than Neo4j, so i think you have more luck on stackoverflow or in the node.js community with this problem.

Just googling, I found
