First off let me say I really like the changes to the leader board and count downs for kom and sprints! I too had the application crash twice on me today after the update-it never has before. Once was on initial startup and the other was halfway through my first lap. I restarted the software and was able to ride for another 5.5 laps with no issues.
I also crashed once today about 25 minutes into my session after downloading update. Just finished going through the green jersey sprint. Restarted and rode for 35 minutes with no problems.
