Dear Members,
I have been trying to calculate the U parameter for my system (CoO2) using hp.x. However the calculation is stopped and appers the next error.

Error in routine scale_sym_ops (8):

I have already checked the example with FeO present in QE summer school and it is works. It means my version of QE works (I am using QE 7.0).
I have attached the input files:
