When I launch with napari -w napari-micromanager I get the following:

0.00s - Debugger warning: It seems that frozen modules are being used, which may
0.00s - make the debugger miss breakpoints. Please pass -Xfrozen_modules=off
0.00s - to python to disable frozen modules.
0.00s - Note: Debugging will proceed. Set PYDEVD_DISABLE_FILE_VALIDATION=1 to disable this validation.

Killed

and then everything closes.

If I run things from ipython and hten open the plugin from the menu then it sometimes crashes and sometimes seems to work, but with a large number of errors:

In [1]: import napari; viewer = napari.Viewer()

It seems that something is going very poorly when displaying this warning which may be a napari problem? Any pointers @tlambert03?
