I am developing a UWP application for Windows 10 Phone. Since some days, when I try to deploy an application from Visual Studio, Iβm asked for a PIN code to connect to the device

In the phone settings, I can call the pairing so that a new PIN code is created for me. But when I enter this PIN, a new dialog box appears informing me that the PIN was incorrect:

If I click Cancel, the deployment is interrupted by an error message:
1> Error: DEP6100: The following unexpected error occurred during boot: "Connecting to device" 30F105C9-681E-420b-A277-7C086EAD8A4E '.':
Strange, but a few days ago I was not asked to enter the PIN code when I deployed the application. :-( So currently the only option I have is to deploy via the web portal. This works, but it is extremely slow: - (
Can someone tell me how to solve the problem or which PIN should I enter in order to achieve deployment?
