The first thing I'd check is that nothing else has that port open. The Serial Monitor, or plotter, or some other terminal program (or even a previously failed avrdude instance that didn't finish and relinquish the port).

Please edit your post, select the output that you showed and click the <CODE/> button to apply code tags; next save your post. This makes the output easier to read and copy.

Which application are you using to upload the file?

For boards with native USB (like your Leonardo(?)) it's normal that the port changes. The application on the Leonardo is running and providing a port. At the moment that a software reset is received the bootloader is invoked which (on Windows systems) will result in a different port. You can monitor that process in Windows device manager if so desired.
