Under the additional html body, I have hidden some user profile fields.

Then under user profile fields, I made a certain field required.
When you do this, if your profile does not have this field, Moodle will redirect you to edit profile and tell you to add the required field.

To access this required field, I need to change the html settings in additional html and unhide the profile field that is now required.

The issue is I cannot do this because I am redirected back to edit profile when I click additional html settings, or any settings at all.

Everyone who logins in is basically locked out of the whole site because of this.
