Unimplemented _get_importer_name in addon / "Failed to unload assemblies"

[dogboydog]

Seems to be related to this issue, which has various causes:

godotengine/godot#78513

I have put in some suggested workarounds while following the above issue, but it still persists. Considering the range of potential causes mentioned, I'm hoping there is an update to the engine that fixes this error. Otherwise if there is any guidance published on how to avoid the error I will implement it.

Workaround: Restart the Godot editor. Re-enable the YarnSpinner-Godot plugin in the project settings if it was disabled.
