I'm writing my thesis in overleaf. I am using \\ to indicate the end of a paragraph. This works perfectly for the entire document, besides for my first numbered chapter (all previous chapters have been defined as \chapter*{}).
My source text looks like this:
\chapter{Introduction}
\section{Glioblastoma}
blablabla.\
blablablablabla.\
blablablabla.\
and shows up as the following:
The problem stops once the next page starts. Does anyone know what could be causing this?

\\\? The empty lines you have imply new paragraphs. – mickep Aug 16 '22 at 11:37\\does not end a paragraph never use it at the end of a paragraph: it forces a spurious blank line and latex will warn you of badness 10000 (which is maximum badness) – David Carlisle Aug 16 '22 at 11:47\par, not \. Anyway, set\parskipto some more than0pt(the default) if you want some space between paragraphs. – Fran Aug 16 '22 at 20:30
