Hi @tam-s1201, 

Seems like you have multiple instances of Device Configurator opened. Can you please try closing all the Device Configurator instances and then try again? If that does not work, can you try closing ModusToolbox and try the same? When you open Device Configurator, it creates a .lock file which prevents you from opening multiple instances.
