I suspect you have forgotten a `}', causing me
to read past where you wanted me to stop.
I'll try to recover; but if the error is serious,
you'd better type `E' or `X' now and fix your file.

The problem was a % in the .bib file. The % sign is used to mark a comment and needs to be escaped or else the rest of the line is interpreted as a comment and thus the } won’t be interpreted and is reported as missing.

Removing or escaping the % (\%) solves the problem. The main issue was that the error points to the wrong reference and so in the end I had to bisect the file, to find the offending entry, as I didn’t know what the problem was.

But I write this up here for the next poor soul who has to deal with the problem.
I also like to mention this tool here: https://flamingtempura.github.io/bibtex-tidy/
It helped me clean up the latex file and might also help fix errors by removing certain characters, removing duplicates and sorting your .bib file.
