Statistical Debugging: If you have access to the source code for the application that is throwing the exception, the first step should be to use Statistical Debugging (StatTime) to profile the application and identify potential causes of the exception. StatTime is an open-source debugging tool created by Apple and is available on Github here.
Check for Compatibility Issues: After profiling the application with StatTime, check for any compatibility issues between the application and the current version of macOS. This can be done by visiting the Developer Support page on the Apple website.
Analyze Crash Reports: If the application is crashing due to this exception type, analyze any crash reports that were generated when the crash occurred. This can be done by opening the Console app on your Mac and navigating to the ~/Library/Logs/CrashReporter folder.
Check System Logs: Another way to debug this exception type is to check the system logs for errors related to the application. This can be done by opening the Console app on your Mac and navigating to the ~/Library/Logs/System.log folder.
Update the Application: If a compatibility issue was the cause of the exception, update the application to the latest version and see if this resolves the issue.
