Please solve the following problem:
Consider the following equilibrium at 395 K:
NH4HS(s) ⥫⥬ NH3 (g) + H2S(g)
The partial pressure of each gas is 0.265 atm. Calculate KP and Kc for the reaction.

@ OP  Bear in mind that at the given temperature NH4SH will be a gas.

Probably you are right.
But it is written

NH4HS(s)
s means solid.

Yes, a rather contradictory question.

Calculate Kp first using Kp expression in which do not include solid NH4SCN.
Kp = KC (RT)Δn
