How Can I Fix this

The noindex tag is appearing on my webpage. How can I fix this issue? To check for this tag, I opened the page source by viewing the source code, and I found this tag: Can you suggest a video to help with this, or explain how to resolve it? I suspect this error is caused by Rank Math because when I deactivated the Rank Math SEO plugin, the error disappeared. How can I confirm this?

that is not in the header, its probably just a setting. check if you see a meta tag in the header section on top of the source that has noindex set.
since you seem to use rank math, check this: https://rankmath.com/kb/how-to-noindex-urls/
just make sure its not set to noindex.
