Latest IDE 2.2.1 update seems to have broken UPDI for me

Using Arduino Programming Questions

Hello.

I was using JTAG2UPDI to program Atmega4808 boards for almost 1 year.

Today I updated the IDE and the UPDI board stopped working. Actually the error is:

         System wide configuration file is C:\Users\...\AppData\Local\Arduino15\packages\MegaCoreX\hardware\megaavr\1.1.2\avrdude.conf

         Using Port                    : COM37
         Using Programmer              : jtag2updi
avrdude ser_open() error: cannot open port \\.\COM37: Access is denied.


avrdude main() error: unable to open programmer jtag2updi on port COM37

avrdude done.  Thank you.

If I close Arduino IDE, and open COM37 with hyperterminal, all is good.

Any ideas?

EDIT1: this is ridiculous. I have to uninstall the comm port driver, reboot the computer to program once the target. After 1st successful program, it can access the port anymore. Is Arduino now written by Egiptians?

EDIT2: I hate what become of Arduino.
