Not sure if anyone else experienced this but after installing the update I couldn’t progress to Zwift itself, the launcher would allow me to select ‘Let’s go’ but then it would close without error. I reinstalled Zwift and now on the 10th attempt it has now just opened the Zwift app - weird!
Not starting at all on a Microsoft Surface Book Windows 10. The launcher is visible in the Task Manager a few seconds and simply disappears. Uninstalled and reinstalled, didn’t change anything.
