Looks like a problem with your UHD (USRP). Could be a number of causes:

Heisenbug: unplug the USRP and then plug it back in.
permission issue: try running srsenb as root.
device contention: ensure no other software is competing for access to the USRP.
driver issue: re-install UHD dev packages, then recompile SRSRAN.

Also might be worth ensuring that your user is a member of the plugdev group, and if not, adding them. I found srsUE behaves slightly differently in relation to SDR/driver selection when running as sudo or not. Based on the filepaths I see in your screenshot, you're running as sudo--worth trying adding your user to plugdev and running srsUE as a non-root user.
