Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
This seems like a conflict with Defender security plugin. Could you please check whether the error can be reproduced when this plugin is disabled?
Looking forward to helping you. Thank you.
