Zwft will not open after a small break

Can someone help me? Im running a PC windows 10. I took a few months off for summer and zwift will not open anymore. I can double click the desktop icon, the WELCOME! screen comes up and I can click on LET’S GO but the next blue screen with the zwift logo comes up for just a second and then it crashes. Any Ideas?

We will need more information to be able to help.

I sometimes get this if I am running in full screen mode and using more than one monitor.

I guess the usual things to try would be uninstall and then do a fresh install in case something weird happened with updates somewhere along the way.
