Overleaf does not display the bibliography in the PDF

[Trysse]

I have an overleaf-project in which the bibliography is not displayed.

The project has a MyBib.bib.

The error message says:

Citation 'alstein_teaching_2021' on page 1 undefined on input line 28.​

link‪./main.tex, 28‬
You have cited something which is not included in your bibliography. Make sure that the citation (\cite{...}) has a corresponding key in your bibliography, and that both are spelled the same way.

I have added the citation using the \cite command and selected an entry from the drop-down menu that overleaf provides.
Any idea what I am doing wrong?

You can take a look. This a link to a mostly empty project to which I have only copied the bib and main file. Here I have the same problem.

feel free to edit in the document.

When I compile it, the first error in the log is this:

BibTeX subsystem: /tmp/biber_tmp_kEni/eaaa1c4ae3a0857b1b28da69b4e55682_15.utf8, line 312, syntax error: found "{2000}", expected "="

Because BibTeX cannot parse the bib file, it is not producing the information required by LaTeX to actually typeset the bibliography, and LaTeX therefore complains about citations being missing and the bibliography being empty.

Always read the error log.

Thanks a lot!
