stuck on exiting when running with pdm

[sujh]

I use pdm to run taskiq like this: pdm run taskiq worker tasks.taskiq.broker:broker -fsd --tasks-pattern="tasks/taskiq/tasks/*.py" --max-async-tasks=100 --hardkill-count=1 --wait-tasks-timeout=25

After a while I entered ctrl+c, then it get stuck. The console printed "Shutting down the broker", but it wouldn't exit forever. I used ps -ef | grep taskiq, the taskiq process was still there.

This issue seems to occur only after the process has been running for a while. If I press Ctrl+C immediately after starting the process, the process exits successfully.

it seems a PDM issue, and only happens in MacOS
