macOS Catalina 10.15.5: Illustrator 24.2 crashes (unexpected quit) during launch

Question

(I found a post about deleting a Wacom framework file, which is not present on my computer.)

Illustrator 2020, in any version, has never worked for me. I had to reinstall the 2019 version to get access to my .ai files. Even now with the 24.2 update, it still unexpectedly quits during launch. I see the splash screen for a bit, then wham-o; it quits. I've been told that this update or that will fix the problem, but nope. I've deleted my user/library/Application Support/Adobe/Adobe Illustrator 24 directory, and that doesn't help.

Wild guess: do you have an Extensis plug-in installed? The crash log indicates it is crashing in a plug-in. If you have any third-party plug-ins installed, try removing them. If that works, the problem is likely with the plug-in. E.g. you might need to get an update to the plug-in specially for 2020.

This is correct. Even though Extensis Suitcase Fusion is the latest version, the plugin was not. I removed the installed plugin, then reinstalled it from the Suitcase Fusion app, and now it works correctly.

Thank you!
