My old motherboard (AB350N-Gaming WIFI) was horribly unstable and would crash anywhere from a few hours to a few days after booting. I installed a new B450M Bazooka V2 motherboard and everything is working great except for the networking. All other hardware is the same.
This is what’s in /var/log/syslog:

I have tried reinstalling the latest kernel with little success. Haven’t dealt with netplan before and am finding it incredibly frustrating. How do I fix the issue permanently? Is there any way to force reset all network configuration settings?
