First, try unpinning sticky in your computer settings. On devices with Windows and Linux operating systems, you need to press the Shift key 5 times in a row to do this. On macOS devices, press Option + Cmd + F5 (you can press Touch ID 3 times on a Magic Keyboard).
Some users complain that AnyDesk sticky keys won’t stop even though it’s disabled in PC settings. This is a program defect that AnyDesk developers have not yet eliminated. Usually sticking stops after the user minimizes and maximizes the connection window or opens the on-screen keyboard and presses any number of keys on it.
In a small number of cases, sticking is due to broken keys. If none of the described methods helped, try connecting a different keyboard to your computer.
