Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
Can you please share any message or error you see on that settings page so we can further check the problem?
Usually, this issue is caused by an existing static robots.txt file present in your root directory. If that’s the case, please delete the file and you should be able to edit your robots.txt in Rank Math settings.
Let me know how it goes. We are looking forward to helping you. Thank you
