Bibliography fails to compile in revtex4-2 when using DIFnomarkup

[omnster]

First, my apologies because this is apparently a revtex issue, not the latexdiff.

When I wrap \bibliography with a null environment, the compilation fails.

Here's an mwe to reproduce:

1.tex:

\documentclass{revtex4-2}
\newenvironment{DIFnomarkup}{}{}%
\begin{document}
This is a reference~\cite{examplereference}.
\begin{DIFnomarkup}
\bibliography{ex}
\end{DIFnomarkup}
\end{document}

ex.bib:

@article{examplereference,
    title = {Example Title},
    author = {Author, First and Author, Second},
    year = {2023},
    journal = {Example Journal},
    volume = {1},
    pages = {123456}
}

When I try to compile the document with

pdflatex 1.tex
pdflatex 1.tex
bibtex 1
pdflatex 1.tex

first, bibtex starts complaining about the Notes.bib file (however, 1.bbl is generated)

Illegal, another \bibdata command---line 4 of file 1.aux
 : \bibdata
 :         {1Notes}

Then, pdflatex fails with

(./1.bbl
! Undefined control sequence.
l.54 ...info {title} {Example title},\ }\href@noop
                                                   {} {\bibfield  {journal} ...

If I comment out the DIFnomarkup lines in the mwe, the compilation runs without errors.

Versions:

pdfTeX 3.141592653-2.6-1.40.25 (TeX Live 2023/Arch Linux)
This is BibTeX, Version 0.99d (TeX Live 2023/Arch Linux)

Again, I am sorry for reporting it here, as this is not a latexdiff issue, but I would really appreciate any help to get rid of the compilation error.
