How can I prevent VBA error 1004 when deleting rows or columns?

Error 1004 during row or column deletion usually happens if you try to delete a row or column that doesn't exist, or if the sheet is protected. Ensure the row/column numbers are valid. If you're deleting a large number of rows/columns, consider turning off screen updating (`Application.ScreenUpdating = False`) and calculation (`Application.Calculation = xlCalculationManual`) temporarily to improve performance and avoid potential errors.
