MKR 1300 and Windows 10 Upload problems

pert:
Please do this:

  • File > Preferences > Show verbose output during: > compilation (uncheck) > upload (check) > OK
  • Sketch > Upload
  • After the upload fails you'll see a button on the right side of the orange bar "Copy error messages". Click that button.
  • Paste the error messages in a reply here USING CODE TAGS (</> button on the forum toolbar).

Sorry, but the upload does never ends automatically. So there is no orange bar, the only message is the one from my first post. After this, IDE is doing nothing.
