As @Rofo noted, it finds too much RF interference (e.g. EMF/EMI/RMI noise), so suggest following this (especially the tips on using a very long USB extension cable to a USB 2.0 port or USB 2.0 hub and not a USB 3.x/4.x port or hub, and even be sure to keep it away from USB USB 3.x/4.x devices and cables due to the fact that they are know to cause EMF interference) → Zigbee networks: how to guide for avoiding interference and optimize for getting better range + coverage
Another related tip (that is also indirectly covered in above guide) is to upgrade firmware before starting.
