Silhouette Studio crashes when creating a new print

If Silhouette Studio closes unexpectedly when you try to create a new print, first quit and reopen the app, restart your Mac, and check for available updates. 

Also check with Silhouette that your version of Silhouette Studio is compatible with macOS 27.0. 

Apple recommends checking for updates and compatibility when an app quits unexpectedly. Apple Support: If an app freezes or quits unexpectedly on Mac

If it still happens, try creating a completely blank document. If that works, the problem may be specific to the original design or action. If Silhouette Studio continues to close even with a blank document, check Console > Crash Reports for a Silhouette Studio report. Apple explains that crash reports contain information about how an app terminated and can help investigate unexpected closures. Apple Support: View reports in Console on Mac

At this point, the cause cannot be determined from the information provided. The Silhouette Studio version, the exact action that causes it to close, whether it happens with every new document or only a particular design, and, if available, the crash report would provide useful information for further troubleshooting.
