wield guess : 

When running the same command line from you prompt rtl starts, or does it need a full path? maybe it's a path issue you have here.

If you try to give the full path to rtl_433 in the driver options (there is one for that IIRC), does it start better?

[KD9JLZ]

I can run the rtl_433 and rtl_sdr on the terminal. I can run it when I am here pi@raspberrypi:~ $ with no issues.

Thank you
