Citations, references and bibliography issues with revtex4 document class

Question

I'm working on a paper using the revtex4 document class (which is mandatory), but I'm experiencing significant issues with citations, references, and the bibliography:

1. First of all, I have to add \RequirePackage[2020-02-02]{latexrelease} at the beginning of the document to avoid the following error: "Extra \endgroup. \document ->\endgroup" which prevents the PDF file from being generated. This issue occurs when working in VS Code but not in Overleaf.

2. Question marks appear in several citations. For example:

"[1] J. D. Bekenstein, 7, 2333 (????), ISSN 0556-2821, URL https://link.aps.org/doi/10.1103/PhysRevD.7.2333." Also, I'm unsure if this is the correct citation format.

3. When adding the "hyperref" package, it introduces strange indentation in the bibliography, and the formatting of equation and figure references changes. Equations transition from simple numbering to a format that includes "equation" and the section number. Figures transition from simple numbering to a strange format similar to equations, where "equation" is also included.

4. If I use the "revtex4-2" class, the bibliography shifts, and the references and citations appear as question marks (note that the bibliography still appears). Additionally, hyperref doesn't work. I am unsure if this format differs visually from the other format, so I am unsure if I can use it for this work.

This is my first post, and any feedback is welcome. I can also provide an example PDF with the desired document format if needed.

Thank you in advance.
