Everytime I open an App, I get a white pop-up window with no content, can't use the App

I've got the same problem on my mac! also something is wrong with creative cloud and I can't log in (error 206). every time I'm trying to log in the creative cloud window is openong and send me to the web site. and this circle is lasting constantly. but I don't have any anti-virus programms, I have switched off brandmayer and my remote connection is sustainable
