Sửa lỗi could not complete the cut command because the selected area is empty. lỗi này là do bạn tạo cái vùng chọn nhưng trong vùng chọn ko pixel nào cả, để ý xem đã chọn đúng layer chưa nhé.
Here are some different possibilities/common pitfalls I’ve run into
Select the correct layer / deselect any existing layer masks
Unlock the layer (double click on it)
Check quick mask mode is disabled (Q)
Make sure there are no odd/small sections of your selection interfering
Invert your selection
Deselect and reselect
Odd layer settings (feather, non-standard tools, etc)
