Thank you for your report.

Could you please try the version on the master branch? The lazy imports have been removed, and they appear to be a problem for pyobjc.

I am having the same problem.

I am starting a "listener" and "hotkeys", and I am getting the same error.

I used the master branch and the problem seems to be solved. Is there a forecast when the next release will be?

Same thing here.
