Upgrade to RDM 2026.1.18.0 64-bit (JIT) Broke vCenter Synchronization

After upgrade to RDM v2026.1.18.0 64-bit (JIT) I'm no longer able to synchronize with any of our vCenters, receiving the following error:

System.ServiceModel.CommunicationException: Error in deserializing body of reply message for operation 'RetrieveProperties'.
 ---> System.InvalidOperationException: There is an error in XML document (7, 696).
 ---> System.InvalidOperationException: The specified type was not recognized: name='CustomFieldStringValue', namespace='urn:vim25', at <CustomFieldValue xmlns='urn:vim25'>.
