You can do something like this:

%%%%%%%%%%%%%%%%%%%%%
\documentclass[12pt,a4paper]{article}

\usepackage[comma,colon]{natbib}
\newcommand\possiblebreak{\hspace{0pt}}

\begin{document}

\begin{thebibliography}{}

\bibitem[{Gulf News}(2021)]{gul21OHB}
{Gulf News} (2021) {Video: A rare migratory bird rescued by Dubai resident
(2021 May 20).}
Downloaded from https://gulfnews.com/\possiblebreak uae/\possiblebreak environment/\possiblebreak video-a-rare-migratory-bird-rescued-by-dubai-resident-1.79307000.

\end{thebibliography}

\end{document}
%%%%%%%%%%%%%%%%%

And then redefine the \possiblebreak in the .cfg file:

%%%%%%%%%%
\Preamble{xhtml}
\renewcommand\possiblebreak{\nobreak}
\begin{document}
\EndPreamble
%%%%%%%%%%

Thank you. The compilation with make4ht passed.

Redefining the \hspace trick would be promising for me (since
I can control the locations of the possible breaks).

I will try with more URLs to see whether Breakurl gives
reasonable results with for platex and make4ht.
(In my ordinary journal submissions, the style files are for
platex or pdflatex, but some journals require .docx.
I want to use the same .bib file to produce reasonable outputs
for the both).

It seems that the Breakurl package inserts some PostScript code in the DVI mode. This causes TeX4ht error. It should be fixed with the attached usepackage.4ht and breakurl-hooks.4ht files.

Regarding the \hspace trick, you could also define a custom command for this purpose, and redefine it to do nothing with TeX4ht. But in general, I think that \url is better. It is weird that it doesn't break with platex. Unfortunatelly I am not familiar with this engine.

The next one (test10-1.tex, also attached) was fine with
platex, but make4ht resulted an error.

I tried with test10.tex and obtained different results
between teX4ht (test10.odt) and platex (test10.pdf).
The long URL line is not broken by platex.
I wanted to specify where to break (such as after &)
by using \hspace{0pt}. This worked as desired in platex,
but not in teX4ht.

If there is a good tip to produce similarly broken
long URLs by teX4ht and platex from the same .tex source,
I would be happy to know it.

TeX4ht doesn't do anything with \hspace. The issue here is that the link is broken into two lines, and LO displays the line break as space:

I would use the \url{} command. It handles line breaks in PDF automatically, and it works correctly in TeX4ht. Moreover, you will get a clickable link.

Unnecessary spaces are inserted at \hspace{0pt}.
