Problem finding getMapfileName in com.mathworks.mlwidgets.help.HelpUtils: null

Hello everyone!
When I run the CVX,It appears " Problem finding getMapfileName in com.mathworks.mlwidgets.help.HelpUtils: null".If there are anyone know the reason?

Is there anybody can help me ? I need help!

Perhaps there is a name conflict somewhere. Try reinstalling CVX (2.2).
