GNUradio errors

I'm running Ubuntu 20.04, GNUradio 3.8.1.0 and a PlutoSDR+ (AD9363), trying to get everything to play nice with eachother. My unit has 2 TX and RX, Ethernet and a better clock.

I can ping and change settings on the Pluto with OpenSSH. I unlocked the CPU and set the Pluto to 9361 2x2 mode. I installed GNUradio 3.8.1 with gr-iio from libiio and libad9361. I then made the pythonpath permanent and GNUradio sees both the iio modules directory and the programming blocks. But when I try to execute either flowgraph from this I get the following errors in GNUradio:


FMCOMMS block error:

And I have no idea where to go from here. I just want throughput in and out to verify that it's working. Any help would be appreciated.
