freezes during loading screen on Mac OS 10.13.5

The loading screen for Java Edition hangs at around 80%. My mac reads that java is no longer responding. This only started happening recently. The only thing that's been updated (as far as I know) is the launcher.

 Note that 1.8.9 and 1.13.2 load perfectly. Could be a 1.14 problem, 1.14.3 also freezes
