Hmm maybe it doesn’t work well with the Microsoft-installed Python version there.
What happends when you manually open a commandline and execute
C:\Users\Andre\AppData\Local\Microsoft\WindowsApps\python3.exe "C:\.platformio\.cache\tmp\get-platformio-1.0.0.py" --no-shutdown-piohome check python’]
(while using the correct username which got corrupted in your post above).
However also the path
Doesn’t look right… .platformio directly in the C: drive root is weird. It’s expected in the C:\Users\<user>\.platformio directory. You aren’t running VSCode as root are you?
Can you quickly reference what solutions you’ve tried from the Github?
