coding error for one user when attempting to manually grade quizzes

• I cannot replicate this error when logging in as another "Teacher" or Admin
• At this time, error is consistent only for one particular user across all of her quizzes past and present while logged in as her
• She was previously able to utilize manual grading feature with same Moodle version

Moodle version 3.9.3
PHP Version 7.3.20
