Warning for the new version of Musescore

If you have a lot of plugins, I suggest making a copy of the file 'config.json'
C:\Users(username)\AppData\Local\MuseScore\MuseScore4\extensions\ -> config.json (WINDOWS)
/home/(username)/.local/share/MuseScore/MuseScore4/extensions/ -> config.json (LINUX)
before loading Musescore 4.5. To make sure that the new version can read it, you should replace all instances of "muse:\/\/
with
"musescore:\/\/
otherwise it creates a new one and you will need to re-enable all plugins.
