CLI Installation fails when excecuting 'postininstall.js / postuninstall.js'

• CLI: 7.0.6
• Windows 10 x64
• Node 12.18.3 / Tried Current and 10.
• Npm v6.14.6 / Tried clearing cache and reinstalling everything including node.

I'm trying to install the cli but can't get a work around.

I tested it with debugger and seems to fail parsing something like 'C:\Users\prego\AppData\Local\Temp\C:\Users\prego\KillSwitches' which is the received path arg at /path-arg.js

And right after this evaluation

const badWinChars = /[*|"<>?:]/
    const {root} = parse(path)
    if (badWinChars.test(path.substr(root.length))

Logs this error in console.
(node:3216) [DEP0016] DeprecationWarning: 'root' is deprecated, use 'global'

I didn't find anything related to this, just one issue with a similar error but tried everything and it didn't work.

Beginne damit, den Windows-CLI-Installationsfehler zu reproduzieren und den von postinstall.js an lib/common/services/cancellation.js und lib/common/file-system.js übergebenen Pfad nachzuverfolgen. Vergleiche den generierten Pfad mit der Validierung in mkdirp path-arg.js und überprüfe anschließend, dass die npm-Installation auf dem angegebenen Node- und Windows-Setup ohne einen ungültigen Pfad abgeschlossen wird.
