Order the rows
Ctrl+H
Alt+R to toogle Regular Expression Symbol ( .* )
'Search': ^(.*)(n1)+$
'Replace with': $1
If the order of lines is important so you can't sort:
'Search': ((^[^S$]*?(?=S)(?:.*)+$)[Ss]*?)^2$(?:n)?
In this case, caution:
Blocks for files with too many lines (1000+) may cause VS Code to crash
and may introduce blank lines in some cases.
