Add null guard for fieldMetadataItem lookup from fieldMetadataItemByFieldMetadataItemId map. When a recordField's fieldMetadataItemId doesn't exist in the map (e.g. during navigation away from a record table view), the lookup returns undefined and accessing .name on it throws "Cannot read properties of undefined (reading 'name')".
