[BUG] Problem with launching napari from recorder environment

[ieivanov]

When I launch napari using the command line from a recorder environment (without actually starting the recorder-napari widget), napari start and works well. However, then I close napari, the command line prompt does not return - instead I have to terminate it with Ctr+C. It looks like there is some process (probably something Qt related?) that is still running.

I just recreated this issue, and I agree that the process should close when napari closes.

Can you take care of this @amitabhverma?

@talonchandler
I can replicate this issue of napari not closing with the following lines on Linux:

conda create -y -n recorder python=3.10
conda activate recorder
python -m pip install "napari[pyqt6]"

As @ieivanov also pointed out, I don't believe this is recorder-napari widget related but possibly pyqt6 since I don't see the issue with pyqt5.
PS: Also, this issue does not seem to affect Windows.

Hm, interesting - does this happen if you don't have the recorder widget installed, i.e. with just napari itself?

Yes, that's exactly what I replicated above. And with pyqt5 it works fine.
