I have tried this three different ways:

1. Fedora RPM via dnf
2. 2.10 source
3. git clone source

Source was compiled using pip3 to satisfy requirements and then to install picard. No errors were reported from compilation. All requirements were satisfied.

The result from all three is picard without a settings function. There is no menu option in either the top or bottom panels. This was NOT a problem in v. 2.9. A new .ini file is created in ~/config/MusicBrainz.

Upon launching picard from the command line (git version), I am getting the following error messages (which don't seem relevant to the issue):
