Keyboard Maestro 8.0.1 Crashing

Isn't this the same issue you posted here?
Issue with macro names in 8.0.1

And @peternlewis identified the issue, and gave you the solution:

Have you applied Peter's cleanup macro to all of your existing Macros?
That would be the first step.

That would be my first suspect. Dragon may NOT be translating correctly and/or creating multiple lines in the Name. I recommend you quit using Dragon to enter Macro Names.

After you do all that, if you are still having the issue, then you will need to do this:

  • Keep a detailed log of each material step you take with KM until you get another crash.
  • Be sure you send every crash report to Peter, and be a detailed as possible on your activities just prior to the crash.
  • Pay very close attention to the name you give every macro.
  • Make sure you can remember the last macro you renamed before the crash.
  • Be sure to check the KM Log files for relevant entries.
    In the KM Editor, goto menu Help > Open Log Folder

Sorry you're still having trouble. Thanks for the update, and please keep a good manual log. FWIW, since you reported this issue, I have tried numerous times to rename a Macro, and have not had any issues.
