How to fix that problem?

Hello,

I am from Poland and I have got a problem. One day I went to play PvZGW2, and something like that happened (photos). I can't click E to enter the changing room or enter the multiplayer portal, because something like that happened. This happens not only with these things, but with all those which need some interaction. Also, I can move using only the keys A and S because, when I click W or D the character does not want to move. Does anyone know how to fix it? Thank you very much in advance.

Karol
