Upgraded to Win 10 and Zwift now crashs during start up

It’s clear Zwift support is non existent. I have been running Zwift on a Windows 7 laptop for a year now. On Thursday (1/9) I upgraded the laptop to Windows 10. When the game starts after signing in, zwift.exe stops working. I uninstalled and reinstalled, same problem. I talked to a support, sent my log file and haven’t heard back. I am going to updated my graphics driver, any other ideas to try. I have had issues before but been able to fix them the same day. I have missed multiple days of riding now and am getting cranky.
