Sign in CHARTS not possible

After updating NG Charts, Navigraph MSFS and NG Data I cannot sign in the Apps and Simlink.
“There is an error determining which application you are signing into. Return to the application and try again.”

Any solution?

…After deleting the Navigraph MSFS Program everything is working normal (automatic).
It seems that the Sing IN Screen disables my Internet connection.
Known Bug?
