When the users click on the "My Assessments & Surveys" module to check the surveys assigned to them, the below error is displayed.

The element type "h2" must be terminated by the matching end-tag "</h2>".

It looks like the assessment_list UI page has been skipped on upgrade due to updates or customizations made. To fix this issue, go to the UI Page record versions, find the Out Of Box Version, right click and choose "Revert to Base System". Do keep in mind, this will remove customizations.
