Exact same problem here. I tried the steps you suggested, @andypeters, but unfortunately the “Allow” button never shows in system prefs.
I ended up downloading the latest version of the VirtualBox software from the Oracle site and installing it. Even though I have never launched VirtualBox and don’t use it, that is all it took… then I could launch Local and it fixed everything. Yay!
Exact same problem here. In Terminal, I get the following read out:

Fatal error: VirtualBox
I’ll try to download VirtualBox as well to see if that fixes it.
Had the same problem after upgrading to OX Mojave and Local to 2.4.2. Also didn’t see a “Allow” in Preferences -> …
I discovered my virtual box is 4.1.x and Mojave will not even allow it to be opened. Downloaded the latest virtual box 5.2.x and now everything works like before. Good luck
Any new solutions to this problem yet? I don’t see an Allow button in general under system preferences. Is there something I can run in iTerm2 to solve this problem?
Okay, I solved this issue at least for myself. My VirtualBox had an update that I needed to make you can install the latest update by going to the link i’ve provided below. Simply install the update and reopen local and everything should work just fine.
