Receiving a "Error Opening Feature class the item doesn't have a definition.

I am receiving a "Error Opening Feature class the item doesn't have a definition. Unable to instantiate class for xml schema type: LocationReferencingDatasetMembership" on our APR enable P_Centerline.

What causes this error? Also, I am only receiving it in ArcMAP & not ArcGIS Pro.

APR uses a 'controller dataset' for linear referencing and the Centerline layer is included once configured with APR. Controller dataset is specifc to ArcGIS Pro and hence you get the error in ArcMap. More info: Feature datasets in ArcGIS Pro—ArcGIS Help | Documentation

Thank Ayan. That was what I was suspecting but I couldn't find the documentation to confirm.
