ansys-api-systemcoupling, the gRPC API package on which PySystemCoupling depends, has had a version update that relaxes its protobuf version requirements and in particular supports protobuf 4.x. This is now needed because the 25.1 SystemCoupling server has had the protobuf updated in the common Python package.
There was also an explicit dependency on protobuf mentioned in the pyptroject.toml here, which I don't think was needed.
