Zwift failing to launch - Windows 10 Laptop

Hi, need some help.
I ran zwift for the past 18 months on my windows 10 laptop without issue. Monday morning, I opened zwift, logged in without issue, clicked lets go, the two splash screens with the images on, but then closed the program down. So never got to the blue screen with the writing. Is I look at the task manager, zwift just closes. I removed Zwift and installed again, worked again until this morning, where the same issue is back.
