Hi. That screenshot looks strange. The names of our folders and files are all in snake_case, but I see several names for folders and scripts in PascalCase in that screenshot. Additionally, we don’t have a folder named “graphic_interface”, its name should be “gui” (we changed that in previous versions).
Are you trying to update a project made with version 1.x of the plugin? And where did you download the version you’re trying to use from?
