I’m going to throw this out there because I’m not sure it made the difference, but on my Mac running Ventura 13.1, in System Preferences, under Privacy & Security > Bluetooth, I explicitly added the BambuStudio application (it wasn’t there beforehand) and ensured it was enabled for Bluetooth.
After doing that, I’ve been able to load up both P1P’s cameras just fine, so maybe the lack of Bluetooth permission here also prevents the IP address discovery.
