Just to reiterate, don’t open piaware on the console.
It is running as a service.
If you want to follow the log:
journalctl -f
Also it seems you accidentally put in a strange altitude when entering the Location.
(also wrong location)
But that shouldn’t matter for getting positions reported with flightaware.
You might want to just configure an existing feeder-id when using a new sd-card:

That means you don’t need to reconfigure the location.
