Did you take a look into this file C:\Users\TAT\AppData\Roaming\Mathematica\Kernel\init.m? Because the error message is concernd about line 1 of it? Is there some unprintable character or something else unusual in it by chance? Often it helps to identical edit a file (in the end it has no visible change). Make a security copy of it before starting to edit it, please. Do you have some non-ASCII characters in path names? Some tools dislike that, despite the fact that Windows itself is Unicode, but some tools are not Unicode.
