KeyboardInterrupt error exiting debug mode in PyCharm

Dashboard, Monitoring & Debugging

I have the same problem. Ray 2.3.1. PyCharm 2021.2.3 Community Edition. Python 3.9.16. Mac OS 13.3. If I try to run ray.init() in the PyCharm debugger, it fails with

More complicated Ray code fails as well. Running in PyCharm without debug is fine. Rebooting the computer does not fix the problem.

PyCharm debugging worked fine on this machine yesterday. I don’t know what has changed.
