Static mesh doesn't cast shadows

Hi everyone, i’ve made my my first mesh with almost decent albedo texture (yay ヽ(◔ᴥ◔)ノ )
But this one doesn’t cast shadows, and honestly i dunno why. Light is movable, and even i’ve tried to rebuild iy, Casting shadows is enabled, every setting is as same as in other SMs. Please can you help me?

Use Static Light, if your mesh is not movable
