This error message appears in Mecway 13.0 if you have a 3Dconnexion controller with an old driver. The solution is to update the driver from here
https://www.3dconnexion.com/service/drivers.html Sorry to keep you on the update treadmill.
Alternatively, you can disable the controller in Mecway through
Tools -> Options -> 3Dconnexion -> Enable controller (requires restart).
