Crashing during game launch? [Windows] [November 2021] [1.19.0] [SOLVED]

We’re seeing reports of Zwift crashing DURING LAUNCH (i.e. not once you’ve reached the pairing or world & route selection screens). If you’re experiencing this after updating to game version 1.19.0 released on November 18, please tell us:

  • What OS platform are you using to run the game app (i.e. Windows10, tvOS, etc)
  • Graphics card model installed in your computer
  • Graphics driver version installed

If using Windows - this article shows you how to find your GPU and driver info


I cannot get past the login following the update - just stops and then closes.
Using old Windows 7 laptop with no issues experienced before the update…

Yes same for me

I have the same problem with WIN10.
Probably the same issue as this topic?
Zwift exits abruptly after displaying “logging on”

It doesn’t look like a login issue.
Seems to crash just as the login screen appears

Same here useless log in then crashes 12hrs for a fix or im gone give my money to someone else


after the update is applied the application stops working
