I compete in the WTRL weekly Team Time Trial on Thursdays @ 1935 ET.
Because each team has to wait x number of minutes after banner drop for their team’s start, we go into the Pairing Screen in order to keep pedaling/keep devices alive, until Go Time. I have had no issues with this since I started using the Pairing Screen technique (last 4-6 weeks or so).
This past Thursday I was to race at both 13:15 and 19:35 ET. Both races had a start delay (jump out of Pairing Screen with the Team) in the 6-8 minutes after Banner Drop. Both times when I hit ‘Escape’ to exit pairing screen, noted Zwift had frozen with the MacBook circle of death. I was out of the race.
I have since tested joining various events and sitting in Pairing Screen for a few minutes before Banner Drop, and within 3-6 minutes either Zwift crashes completely, disappears from screen, or freezes. Now I see the radio signal around ANT+ stops moving/freezes. (I disabled BLE since it was intermittent with the new MacBook and gave up on it).
I have removed all devices from USB - C (remote keyboard/mouse), reset NVRAM, reset SMC, uninstalled Zwift, Reinstalled Zwift, Verified Zwift can write to Documents Folder, verified I’m on T2 chip, Catalina 10.15.4.
I have handy a few crash dumps for the times Zwift crashed out - and likely there are Zwift app logs either somewhere on my hard drive and at headquarters.
The next race is in a few days and I desperately hope for some help!
