App crashes on launch if it loads a managed Factorio instance or modpacks.json MacOS 12.1

Whenever I try to start the manager, if I have managed to manually create a managed install (as the download/import process is separately broken) or if I have not deleted the modpacks.json file, the app immediately crashes.

It appears that you are running into the 'only main thread does UI' limitation placed on cocoa apps, but I don't know why this is only an issue with a loaded factorio instance or modpacks file.
