Have upgraded to the latest version of Photoshop CC yesterday. However, today when editing in photoshop it works fine until I try to save. When the windows explorer box opens for me to name my file photoshop stops working and closes.
Im running Windows 10 and last night I found there was an update. For some reason it hadn't prompted me - I had to go looking and check for updates. However, having run that update it seems to be ok again so maybe could be your answer too?
