We have released Picard 2.2.1, which fixes a couple of issues reported here since the 2.2 release. Thanks to everybody here for your feedback and for reporting issues you encountered. The details are in the blog:
A special note to users of the Classical Extras plugin, which causes crashes when opening the options dialog :
Please download the fixed plugin manually from https://picard.musicbrainz.org/api/v2/download?id=classical_extras
Then replace the existing classical_extras.zip file in your plugins folder with the new one. On Windows the plugin folder is in %LOCALAPPDATA%\MusicBrainz\Picard\plugins .
Depending on your username this is something like C:\Users\MyUserName\AppData\Local\MusicBrainz\Picard\plugins
