Probably not the solution for you unless like me you have a German keyboard or changed your language settings – I just recently had this same problem living here in Austria and working off of a German keyboard – I changed my language settings to English, forgetting that I have a German keyboard (or not realizing it matters) whereby the z and y keys are switched- after resetting back to German it works again…or I suppose I could also have tried apple+y
cheers,
