Nothing saves. Crashing?

I’m relatively new to Zwift. Been using it for a few months now. The last two times that I have completed my workout, when I click “save & exit” the app shuts down and nothing is saved or uploaded. I have been able to recover the fit file and upload to TrainingPeaks and Strava, but everything on zwift is lost. Any help would be appreciated.
I’m using:
MacBook Pro OS 10.14
Wahoo Kickr 2017 version
Pioneer power meter for cadence via ANT+
Garmin HRM Tri heart rate via ANT+

Hi Nate,

Our support team will need to investigate your Mac Crash logs, so I’d recommend reviewing this article from the Zwift Support Hub. Skip down to the If You Have a Mac section, then submit a support request to our team and send the Mac Crash logs.
