When you paste an image that you have on the Windows clipboard, it saves it as "image.png" and therefore when you paste another image again, it cannot add it because that name already exists.

It should give a different name like "screenshot20240123-174533.png" adding, for example, the date and time, so that the file is not repeated and save ok
Congratulations for the project
