Solution

Try these troubleshooting steps in order; if you continue to have problems, you can submit a support request and Technical Support can help you.

Letting the type core start before opening Connect Fonts or Suitcase Fusion

The type core is the background process that activates and deactivates fonts for Connect Fonts and Suitcase Fusion. Sometimes the core can't respond properly because it takes longer than expected to start, and you get this error code as a result. Close Connect Fonts or Suitcase Fusion, wait 5 to 10 seconds, and open it again.

If you set Connect Fonts or Suitcase Fusion as a login item in macOS, it may open before the type core has started. There's no way to set login items to start in a specific order in macOS; remove Connect Fonts or Suitcase Fusion as a login item and open it after you've logged in to macOS.

Control-click on the Suitcase Fusion icon in the Dock
Uncheck Options > Open at Login

Reopening windows when logging back in

When you restart your Mac, macOS will ask if you want to reopen your open applications and windows. This can have the same affect as setting Connect Fonts or Suitcase Fusion as a login item; when restarting your Mac, uncheck "Reopen windows when logging back in" before clicking Restart.

To run the script, double-click the .command file. If macOS warns you that the script can't be opened, Control-click on the script and select Open from the dropdown menu. You'll get a different warning dialog with an Open button.
