Phone unable to USB tether

Hey guys, I'm trying to connect my phone to my PC to create a LAN between them via USB tethering, but sadly it's not working

My phone is the samsung galaxy A71

With my phone plugged in and USB tethering enabled, when I run nmcli it shows:

enp9s0f3u1u1: unavailable
        "Qualcomm FP3"
        ethernet (rndis_host), hw, mtu 1500

As you can see, it is unavailable. Digging a bit deeper and running ip addr it shows:

13: enp9s0f3u1u1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff

As you can see, the mac address is all zeros and from what I have read, this locks up the networking part since it refuses to work with it. Does anyone know a way to remedy this issue? Currently, I can use macchanger to change the device's mac but this is cumbersome, manual and not seamless, I would ideally like to be able to plug in my phone and that's it, just like any other phone

For reference, plugging in my brother's huwaei phone and enabling usb tethering leads to the expected results of it working, and plugging my phone into a windows machine also shows it working. Any help would be appreciated, thanks

Re: Phone unable to USB tether

No idea how to make the phone behave, but you can certainly automatize the macchanger action?
