Hello Local by Flywheel folks

I am using the Local (Beta) Version 5.0 5+900 which appears to be the latest beta. It was working fine a couple of nights ago, however, that was also when I updated my mac to Mojave (v 10.14) and after that I didn’t test Local / my local sites. So now I can’t start up anything locally… I checked every error log I could find - looked at all the logs, but I don’t know enough about backend stuff to understand what is going on.
