Hello @odommo,
Thank you for contacting the support and sorry for any inconvenience that might have been caused due to that.
Please follow the instructions mentioned here:
https://wordpress.org/support/topic/wordfence-isnt-compatible-rankmath-plugin/#post-14586866
If that does not help and assuming you are using the latest version of all the plugins, themes, and WordPress (please update if not yet), it would seem like a conflict with one of the plugins or the theme you are using.
To determine that, please follow this troubleshooting guide:

Only the site admin would know and your users won’t be affected by this troubleshooting.
Looking forward to helping you.
