Hi @masouddarvishi1992
I’ve tested your code, and it appears not to be working. I suggest that you create an issue on our GitHub repo here. This way, our developer can review it and provide further insights.
You can also ask this questions on the #developers channel of the WooCommerce Community Slack. Many of our developers hang out there and will be able to offer insights into your query.
In the meantime, you can disable marketplace suggestions under WooCommerce → Settings → Advanced.
I wish I could help more, but hopefully, this gets you going in the right direction to get the job done.
