I made a copy of my latex project for version control purposes and it broke the bibliography in my compiled document. All the citations are question marks and the bibliography is not listed. Nothing is changed in the document except for the title used by overleaf (original project name - copy).

The original and the copy are using the same latex compiler and tex live version. I also tried downloading the zip of the project and reuploading it and got the same problem. The tex file and the bib file are in the same directory.

For now I am just going to store a download of this version and modify the original directly because I don't know what else to do. If anyone knows what the issue is or what I could do please let me know. If there's other information I should give please let me know.

I had this exact same problem in Overleaf and just solved it. For me the original project was using TeX Live version 2017 (Legacy), however these settings do not carry over when duplicating a project. Therefore the duplicate was using the default TeX Live version 2020. Changing this back to 2017 (Legacy) in the Menu -> Settings -> Tex Live version solved it.
