I get the error " You can't use `prevdepth` in horizontal mode" while using `algorithm2e` package

I use a separate .tex file for every section in my document.
One of these documents require an algorithm to be written. I use algorithm2e package to do so.

Here is my MWE (algorithm is taken from this website):

%!TeX root = Section2

%Section 2
documentclass[crop=false]{standalone}
usepackage{enumerate,tikz}
usepackage[ruled,linesnumbered,vlined]{algorithm2e}

begin{document}
    
subsection{Simple algorithm}
begin{algorithm}
KwIn{A sequence of integers $langle a_1, a_2, ldots, a_n rangle$}
KwOut{The index of first location witht he same value as in a previous location in the sequence}
$location gets 0$;
$i gets 2$;
While{$i leq n$ textbf{and} $location = 0$}{
    $j gets 1$;
    While{$j < i$ textbf{and} $location = 0$}{
        % The "u" before the "If" makes it so there is no "end" after the statement, so the else will then follow
        uIf{$a_i = a_j$}{
            $location gets i$;
        }
        Else{
            $j gets j + 1$;
        }
    }
    $i gets i + 1$;
}
Return{location};
caption{{sc FindDuplicate}}
label{algo:duplicate}
end{algorithm}

        subsection{Advanced algorithm}
    end{document}

The output of the algorithm looks like this:

The indentations and the line numbers are all messed up.
Below are the error messages I get, and I assume the main problem is so called prevdepth command which is used somewhere automatically and causes incompatibility with some other environment.
