[SOLVED] PlatformIO not compatible with Python 3.9.5?

Hello all, I try to install Platformio under VS-Code.

I start from scratch install first VS-Code :

Version : 1.56.2 (system setup)
Commit : 054a9295330880ed74ceaedda236253b4f39a335
Date : 2021-05-12T17:13:13.157Z
Electron : 12.0.4
Chrome : 89.0.4389.114
Node.js : 14.16.0
V8 :
OS : Windows_NT x64 10.0.19042

I’m using Python 3.9.5, is there an incompatibility between both ?

Result is :

Thanks for ideas !

So what does the developer console say?

Not sure is usable (for me ! ) :
BTW is there a method to (try) to install a previous version ? I’m using v2.3.2 of PIO ?
I try to install V2.0 (deinstalling the other) : Same result !
So, it seems files (empty) are conflicting with PIO on : C:\Users\Your_User_Name\AppData\Local\Microsoft\WindowsApps
I’m unable to delete … Using Shift+Delete delete the files !
I restart the PIO installation, now seems OK !

This solve my problem !
