How did you determine

```auto
[mcu]
serial = /dev/serial/by-id/usb-Klipper_stm32g0b0xx_500046001450415833323520-if00

```

The klippy.log is basically very clear (Split into two lines for better readability):

```auto
mcu 'mcu': Unable to open serial port: [Errno 2] could not open port /dev/serial/by-id/usb-Klipper_stm32g0b0xx_500046001450415833323520-if00: 
[Errno 2] No such file or directory: '/dev/serial/by-id/usb-Klipper_stm32g0b0xx_500046001450415833323520-if00'

```

`No such file or directory` means exactly this: This path does not exists and so Klipper cannot connect to it.

Follow the setup procedure, e.g. [Installing Klipper with KIAUH](https://klipper.discourse.group/t/installing-klipper-with-kiauh/10734) and determine the correct path. If nothing turns up, then probably the board is not correctly flashed. [Issues flashing the printer board](https://klipper.discourse.group/t/issues-flashing-the-printer-board/14015) gives some more hints in such a case.
