After searching for the problem on my PC's side, I ran out of ideas. It had to be some error on the MCU side. What solved it for me was putting the MCU into update mode (in CubeIDE > Help > ST-LINK Upgrade) and even though the latest version was programmed already, I updated it again which probably caused the right kind of reset on the MCU and it worked fine after.

Like RRei.1 said you can use tcp view.

You can get it here, it's the new improved version better interface and yopu can filter for ports.

Just use Sysinternals TCPView (or similar tool), find the port in the list and 'Close Connection'.

Try programming again.
