Hello,
After experiencing this bug (constant freezes on start of ride), I tried a number of different patterns.
Do those experiencing the bug keep their power supply plugged in?
I’ve found that most of my crashes stop when I remove my power supply from my Macbook, I’ve had 3 spins using the Macbook and had great success when the power isn’t connected.
I had 66% percent on the battery when I did my last cycle and got a hour out of it without crashing so that’s rather positive and 45 minutes a few days before.
I will try again later but with apps open like Spotify and will feedback, if successful, I will then attempt to use Zwift fullscreen (as I read that full screen may cause the crashes).
I hope this helps.
