Where are you seeing the version 2.4.0? That version is rather old and definitely does not work with Godot 4.0.
Is that based on the plugin configuration file? If so, the following plugin config file is probably out of date, as it’s likely I forgot to update it. If it runs in Godot 4.0 in any capacity without needing the project converter though, it is version 2.7.0 as that is (currently) the only version with Godot 4.0 support.
