Hi @simonjayhawkins for fixing this issue should i check for Concatenation operation here and use np. concatenate() here ?

  if should_extension_dispatch(lvalues, rvalues) or isinstance(rvalues, Timedelta):
        # Timedelta is included because numexpr will fail on it, see GH#31457
        res_values = op(lvalues, rvalues)

    else:
        with np.errstate(all="ignore"):
            res_values = na_arithmetic_op(lvalues, rvalues, op)

    return res_values

not sure. wait and see what others think. I can't see a change note or deprecation for the change in NumPy. @pandas-dev/pandas-core

Sure will wait for the others to respond
