Not launching on Mac Mojave 10.14.3 (18D42)
Downloaded and moved .app into Applications, then launched from there.
It appears to start launching but never completes. OS registers it as 'Not responding' in Activity Monitor.
Downloaded both stable release 5.6.0 and latest nighly build, both appear to have the same issue. Attached are logs from Activity Monitor.
