Yesterday everything worked fine. Nothing has been changed.
I reinstalled Android Studio. The problem is still here.
Help me please!!!

I think's it a bug in some latest version of something
My username consists of cyrillic letters
Which explains C:\Users\?????\.gradle\
It can't load any files under the path C:\Users\?????, so it fails.
Solution until whatever bug is fixed: Make a user account without cyrillic letters
