Gnuradio can read the old pfb.grc fine. It can also export a top_level.py ok. The problem is CygnusRFI.py can only work with the old top_level.py not the new one generated by recent GNUradio.

Update CygnusRFI.py to work with latest gnuradio.

The new top_block.py export from gnuradio works for the first pass. But for the second pass it fails:

usb_claim_interface error -6

It thinks something is using the device. Probably itself. It releases the device, so script can be re-run immediately.
