[BUG] Shift key blocks character output during integrated MultiViewer F1 sign-in

[KingPungy]

During the Sign in process when choosing the sign in option that is integrated inside MultiViewer the shift key blocks any character from showing up in any textfield.

i.e.
When trying to type @ when trying to enter your email or any capital case character it stops any input. which makes it impossible to enter a valid password with such characters in it.

i have no clue why this happens but it also blocks those characters from being typed in other applications.
it's like it hijacks your keyboard output.
only when closing the entire application does the control over the keyboard return.

btw. i've managed to sign-in by closing the app writing the login info in another app text field and copying them into the text boxes of the F1 sign in.
