Python – Jupyter Notebook Opens Empty Browser

Before I've installed python 3.6 and update all (conda update –all) my Jupyter Notebook just stopped to works. When I launch it, just an empty browser page appears. I tried all solutions that I found, but they don't work. I have deleted %USERBLABLA%, clear cache and cookies, uninstall and install it again and it still doesn't work. Browser console prints this errors:

Refused to execute script from '<URL>' because its MIME type ('text/plain') is not executable, and strict MIME type checking is enabled

Uncaught ReferenceError: require is not defined
