Well, I have uninstalled the program three times. Then installed via the Zwift website, once. Once from my original download and the final was a new download.All three times it automatically update to the Nov. 18th update. Start the program and it crashes at login.
Could Zwift please email me directly to resolve this problem.

Crashes after log in screen
Same problem here. All worked fine immediately prior to the update, then updated at the end of a ride and Zwift crashes on login immediately after the blue screen. I also received the firewall error message first time round. Core i7, Windows 7 and Intel HD 4000 - all worked well this afternoon.

Please continue to report the Windows OS version, GPU card model & graphics driver as in the first post above. All of your reports have helped a great deal to identify what’s happening.

I’m going to Montreal for the weekend… Hopefully by Monday it’s sorted. I’ll be needing my Zwift fix by then.
I have the Zwift start up crash also.
Zwift was working fine before the update.
OS: Windows 7 64 bit Professional.
Graphic card: HD Graphics 3000.
Driver version: 9.17.10.2849
I hope this information helps.
I’m trying to sign in to do a ride, but I cannot sign in.
I guess no Zwifting for me today. 
P.S. (extra information):
I think that my firewall is now blocking Zwift also.
I hope that this extra information helps also.
Side note:
I see that the “gstatic” issue has not been fixed either
(but, that is another topic).
Same issue. Updated and haven’t been able to get past the “logging in” page.
OS: Windows 7
Intel(R) HD Graphics Family
Driver: 10.18.10.3412
Last few lines of log is also the same as some mentioned above:
[21:34:22] NETWORK:Got the list of worlds
[21:34:22] Experiment service disabled assert abort
[21:34:22] ERROR: ZwiftApp Crashed
UPDATE: We released the fix for this in version 1.19.1 (1.0.100133) for Windows only. Please update at your earliest convenience.
