Hi everyone, since I have installed the newest Betaflight configurator App Version: 2025.12.2 I'm not able to connect to my FC anymore. With the older version of the Betaflight configurator there was no problem. When I try to connect to my SpeedyBee Mini FC there is an error message - Failed to open serial port. Regards, Patrick
