ZwiftApp Crash post-race while saving

After finishing today’s race ( ZwiftPower - Login ) I hit save and app closed down without warning or error message.
Re-start of app did not open up un-saved activity notification, and fit-file seems to have disappeared.
I’m on the results list in Companion (on other participating racers activities), but no activity is seen on my profile (obviously not on Strava either).
The live data seems to have gone through to ZwiftPower accordingly.
