Hi @승현31643923i4ip , thanks for reporting this. At the moment there is an known issue when the filepath contains non-Roman characters that prevents the plugin for loading. Our next release will have a fix for this that allows users to define another filepath for the integration tools that does not contain non-Roman characters.
In the meantime, if you are able to you can try creating a new directory where the User and AppData file paths contain Roman characters only and installing Blender and the add-on there.
