Hi Nguyen,
One easy solution/workaround to this would be to change your light from ‘Static/Stationary’ to ‘Moveable’ - Shadows from moveable lights are calculated in real-time, so no baking required! (Be careful with too many moveable shadow-casting lights though, they WILL hurt performance)
If you want to stick with baked lighting, I’d try and level-up your knowledge on lightmaps (Does the lightmap UV for the wall look sane?)
Hope that helps!
