Development Tools Uploading

Hi, I am working with Arduino Pro Mini board (3V3, 8MHz) that has an FTDI interface; I have problems to upload sketches to it when I use IDE 2.3.3 (Windows doesn't see the COM). On the contrary, when I use IDE 1.8.19 everything goes. The error is:

System wide configuration file is "C:\Users\Paolo\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino17/etc/avrdude.conf"

     Using Port                             : COM5
     Using Programmer              : arduino
     Overriding Baud Rate          : 57600

avrdude: ser_open(): can't open device "\.\COM5": Accesso negato.
avrdude done. Thank you.

If serial plotter or serial monitor are open, please close them.

If serial plotter is open, close it. If serial monitor was not open at that point, open it and close it.
