[Bug] npm install utam fails with errno -4048 Error: EPERM: operation not permitted, mkdir 'C:\'

I have switchted to node v20.7.0 and npm 9.7.1. I changed the path for prefix: npm get prefix returns C:\Users\<myuser>\AppData\Roaming\npm.
I tried to run npm update and it failed with the same error basically: EPERM: operation not permitted, mkdir 'C:\'.
Then i did run npm install -g npm@latest and now have npm -v 10.4.0. I tried npm install jasmine as local admin and as normal user and it failed with EPERM: operation not permitted, mkdir 'C:\'.
So i assume this is an issue with my box and not with utam.
