Error when trying to update ZBT-2

Configuration Zigbee
1

I just plugged in my new ZBT-2 and after going through the process, of it wanting to update the firmware I’m given this error:

Zigbee firmware failed to install, check Home Assistant logs for more information.

Log:

Traceback (most recent call last):
  File "/usr/src/homeassistant/homeassistant/components/homeassistant_hardware/util.py", line 421, in async_flash_silabs_firmware
    await flasher.enter_bootloader()

    await self.probe_app_type()

    raise RuntimeError("Failed to probe running application type")

The above exception was the direct cause of the following exception:

                                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    )
    ^

    raise HomeAssistantError("Failed to flash firmware") from err
homeassistant.exceptions.HomeAssistantError: Failed to flash firmware

Can someone make sense of that, and perhaps point me in whatever direction I need to go to fix this?

Thanks in advance
