Dan, Possible to try older kernel releases? Like 4.15?

When I clicked it again to reenable it, my networking did not return. After unsuccessfully poking at it for a while, I rebooted and saw the below (and still no networking). `rmmod r8169; modprobe r8169` had no (apparent) effect, nor did further reboots. I rebooted onto two different kernels, both exhibited the same behaviour: 5.4.0-21-generic, 5.4.0-26-generic. I was finally only able to restore networking by _rebooting into Windows_ and then rebooting back into Ubuntu. (My supposition is that NetworkManager/the kernel set *waves hands* something on the network card that persists across boots when it was disabled, and that wasn't correctly unset when I reenabled networking (or on following boots), but Windows _does_ correctly handle that case on boot, and reset it to a working state.)
