Hello, It might be because the Hartree-Fock exchange at one point in space depends on the density at all other points in space (non-local operator). So, as I understood, and strictly speaking, to get a valid density with HF or hybrid functionals, one needs to run a full SCF. Maybe (needs to be checked) QE is internally preventing NSCF with hybrids for that reason.
