Local (2.2.4 on Mac, 10.14) won't start/update (FIXED)

FIX: instead of following update prompt I just downloaded a fresh copy manually and replaced the app. After updating Virtual Box the site server started normally.

Hangs while “Starting local machine”…

Says there is an update. I accept. Download and wait for local to restart but then gives me same “new version of Local is available!” message all over again while still not starting local machine.

Log says:

Oct 30, 2018, 1:05 PM EDT - info: [main/docker-machine] (local-by-flywheel) This is a known VirtualBox bug. Let’s try to recover anyway…
Oct 30, 2018, 1:05 PM EDT - warn: [main/docker-machine] Error setting up host only network on machine start: The host-only adapter we just created is not visible. This is a well known VirtualBox bug. You might want to uninstall it and reinstall at least version 5.0.12 that is is supposed to fix this issue

Help please. I don’t know how to do any of that.
