Apologies for the mistake — it was caused by a version mismatch between my local environment and the GitHub workflow. I've fixed the issue.
Thank you for checking and reviewing it, and feel free to let me know if anything else needs to be addressed!

I don't have access to my laptop so I'm unable to test the change, however everything else looks good to me.

@isnandar1471 Another issue is the wrong IcoPath field which can cause plugin icon fetching issue.

image

It should be assets/logo.png instead of assets/icon.png.

Regarding the error "No module named 'psutil._psutil_windows'," I've tried to fix it. This error occurs because GitHub Actions builds the plugin in the wrong environment (using Linux), instead of Windows.

@isnandar1471 Another issue is the wrong IcoPath field which can cause plugin icon fetching issue.

image It should be `assets/logo.png` instead of `assets/icon.png`.

https://github.com/isnandar1471/flow.launcher.plugin.used-by/blob/23ca6cce6debcafb0e48fdd72d6f4f9c24b86c97/plugin.json#L10

And regarding the plugin image not appearing in the settings, I've also fixed it.

Thank you for sharing the error. I really appreciate feedback.
If you encounter any other issues, please contact me again.
