hi I'm typing my research in LaTeX. I have committed this error in the source code, which I have snapped, because of which I cannot compile any longer. pls help me to correct and not commit such an error again. thank you.

full error statement:

slide_Template.Tex|warning|line336|\begin{center} on input line 53 ended by\end{document}.\end{document}

*THE NEXT WARNING THAT FOLLOWED WAS;*

slide_Template.tex|warning|line26|Token not allowed in a pdf string(PDFDocEncoding):(hyperref) removing '\\'

pls I have solved it. I figured out the problem. I forgot to close a command. Thank you.
