Public summary

Objo Studio can fail to start on Linux after the Avalonia 12 update. On Fedora, launching Studio from Rider exits during Avalonia X11 initialisation with a System.TypeLoadException for Tmds.DBus.Protocol.Connection.

Expected behaviour: Studio should start from Rider on Linux as it does on macOS and Windows.
