Looks like a test has started failing on main.

looked into this quickly but it's a little tough, some notes from digging, will get back to this a bit later

running pytest (as happens in the action) I get the same error

====================================================================================== short test summary info ======================================================================================
FAILED dask_ctl/tests/test_lifecycle.py::test_snippet - RuntimeError: Event loop is closed

but when I run the test by itself using the pycharm test runner the same test passes

Launching pytest with arguments test_lifecycle.py::test_snippet --no-header --no-summary -q in /Users/aburt/Programming/dask-ctl/dask_ctl/tests

I also see errors when running the test saying that 8787 is already in use but I've closed down anything dask related - this may or may not be related/part of the problem

Pinning has resolved this, going to open a new issue to track updating to a newer version.
