I discovered the solution to my question. The toast notifications have been suppressed by Windows 10 Action Center. At the bottom right corner, click the Action Center icon. For my PC, the "Quiet Hours" setting was turned on. After I disable "Quiet Hours", toast notifications can appear.

The python library win10toast works perfectly fine after Action Center settings are correctly set.
