Hi n.Wright,
Please check for Windows update, Microsoft has released an update regarding flash players on Windows 10.
Further, as S.Sengupta suggested, please uninstall and re-install the program to take a check.
If not working, then we may consider to check for additional errors through Event Viewer, or take use of the process monitor to find out which steps casues the application to crash.
