OK, I would run it using only one RTL radio at a time, i.e. just start the Nano or just start the FlightAware. If you get the same failure, then run the other RTL and see if that one fails.
BTW, what version of W10, and what are your PC hardware specs?
A screenshot of your RTL radio specs found in Device Manager under Universal Serial Bus devices>(RTL Radio name)>Driver tab>Driver Details would help
