It seems that the DICOM listener broke due to the recent switch to Python3.

For now, you need to disable the DICOM listener by copy-pasting this to the Python console:

```
slicer.app.settings().setValue("DICOM/RunListenerAtStart", False)

```

After you restart Slicer, everything should work well.

We are doing large refactoring work in Slicer nightly builds, so unless you rely on a recent fix or improvement in the nightly builds, it may be better to use the latest stable version for a few more months.

Thanks for reporting 👍

Should be [fixed in the next nightly](http://viewvc.slicer.org/viewvc.cgi/Slicer4?view=revision&revision=28186).

It might be useful to post a similar message to the download page as well…

Agreed - let me try again.
