Recently I have installed new Ubuntu 18.04 and made minor set ups. But, it keeps logging out after certain actions made. Namely, I have installed google chrome browser and restored previous ubuntu 15.04 browser data and extensions. When I want to download video or something via downloader extension, the system stops and throws me back to log in view. After Loging back, all windows and applications are closed. The same this occurs if I want to remove or run installation of some applications. My suggestion is that, it keeps logging out if system faces some errors. Need your help. Thank you beforehand

This is detailed logs when this happened:
