CrazyTalk 8 should run great under Windows 10. My own installation under Windows 10 is extremely stable and never crashes so unfortunately it is likely a system related issue.
Can you share a some information about your system specifications including the graphics card being used. Thanks.
Just to add, do also make sure you are using the latest version of CT8 which is 8.13.
