Unable to transfer sketches to an Arduino from Windows 11

[Gilles]

Hello, recently I have no longer been able to transfer sketches with IDE1.8.16 from my Windows 11 PC. USb FTDi driver version 2.12.36.4
The driver on my other computer is wch.cn version 3.5.2019.1 computer under win10
This is the one I also had before under Win 11 but probably an update.. I can’t reinstall this driver version..
Has anyone encountered this problem before and have a solution?
THANKS

Hi,
check if another process uses the port.

netstat -an

Bye Renzo

Apparently not used by anything else.
I installed the old driver and suddenly it works again (damn Windows 11 and the others too!)
Thank You
