I also had a problem on my HP Laptop, I did notice that Windows had a update, as did Trend Micro, and also zwift has also, would seem all these caused a problem

Booting me out on launching
I cleared edge
Uninstall Zwift
Re installed
Put mute mode on on trend micro security
It opens and seems like it will launch
But once you press ok
Zwift just dissappears
