1. Navigate to Manage Configuration UI.
2. Attempt to open the target custom MDF UI.
3. Observe the error: "Cannot read properties of undefined (reading 'render')".
4. Open People Profile and navigate to the relevant object/card.
5. Observe the error message: "Looks like something went wrong. Please try again. If the issue persists, contact your system administrator."

• Misconfiguration in the custom MDF UI: the resolver of the baseObject was set to a field. Setting the baseObject to any field is invalid and causes the UI to fail rendering.

1. Open the affected custom MDF UI in Manage Configuration UI.
2. Locate the baseObject configuration and its resolver/mapping.
3. Remove any resolver mapping that sets the baseObject to a field value; ensure the baseObject is correctly defined for the object and not mapped to any field.
   
4. If available, restore the UI from a known-good backup, or import the backup UI to overwrite the misconfiguration.
5. Save the configuration.
6. Validate the fix: open the UI in Manage Configuration UI and access the corresponding card in People Profile to confirm it renders without errors.
