This issue can be occasionally solved by first stoping NetworkManager and then starting it (two separate commands). However, simply running restarting NetworkManager (one command) doesn't work. Below is the command I ran in sequence that worked:
sudo sv exit NetworkManager
ok: NetworkManager: runsv not running
sudo sv start NetworkManager
ok: run: NetworkManager: (pid 3231) 16s
sudo sv stop NetworkManager
ok: down: NetworkManager: 1s, normally up
sudo sv start NetworkManager
ok: run: NetworkManager: (pid 3426) 1s
Unfortunately, the same set of command didn't work several minutes ago. That's why I said "occasionally".
Below is NetworkManager's latest log:
