Help suppressing connection msg error -> "Could not find a connected Meadow with the serial number 335F3xxxxxx"

Hi everybody, I’m hitting the below issue when flashing the os, I’ve updated the drivers to use WinUSB as per the setup guide and have dotnet sdk 6 installed with the CLI tooling, uninstalling the device from device manager and drivers but I can never get further than the below issue, any ideas would be greatly appreciated.
