Unfortunately, older IDEs do not have ProjectTool available to them, and the project format does change over time - with 2024.2 being the last major change point. What you can do instead, is to use ProjectTool in a current IDE, and downgrade the YYMPS to a LTS-22 YYP Project.

You can then open the YYP as a normal project, or use the Import from YYP option. We will look into supporting downgrading into YYMPS as well, but this should let you get on just now.
