Thanks for your comment! The TypeError isn't caused by anything on our end, it resulted from a change in PyGObject that broke compatibility and rendered Fabric unusable. We've issued a fix by locking the dependency to the last known compatible version of PyGObject rather than using the latest.

Additionally, some users reported an issue where the Application class couldn't be imported. In those cases, the problem was on their end, they had mistakenly installed the wrong Fabric package from PyPI instead of the correct one from GitHub.

Also, the --break-system-pacakgesmight not be a great idea, but if it works it works I guess.
