Your error:

mcu 'mcu': Unable to open serial port: [Errno 2] could not open port /dev/serial/by-id/usb-Klipper_stm32g0b1xx_11001A0005504E5238363120-if00: [Errno 2] No such file or directory: '/dev/serial/by-id/usb-Klipper_stm32g0b1xx_11001A0005504E5238363120-if00'

Likely something from here: Issues flashing the printer board
