"gamed quit unexpectedly" Error Message

Multiple times now I have started Zwift and, after loading and getting ready to ride, I get the error message “gamed quit unexpectedly” (that’s not a typo on my part, it says exactly that: “gamed quit unexpectedly” in all lowercase).  Zwift keeps working but that error message pops up randomly every 5 seconds or so. If I close Zwift, the error messages stops. Once I reopen Zwift, the error messages starts again. I have to restart my computer for Zwift to stop throwing those error messages.  But a few days later, the messages will come back.

On a side note, I also have that “25km remaining” still on my login screen even though I’m a paid subscriber.

Computer:
MacBook Air
macOS High Sierra Version 10.13.2

Zwift version 1.0.23773

Can’t help on the first problem Michael but the second ‘25km’ thing is a known issue and is being worked.

It may be worth opening an official help ticket for the ‘gamed quit’  problem.
