Insert Citation from .bib-file not possible in VS Code, but works in RStudio

Hi!

I am currently switching from RStudio to Positron. I like to write text in the Visual Editor and frequently use the "Insert Citation" option. I prefer not to use Zotero within RStudio/VS Code, but rather export a bib-file from Zotero and keep it updated, provide it in bibliography: in the YAML-Header and choose the citation via the "Bibliography" Section in the "Insert Citation" window. It works perfectly well in RStudio (see the image with the white background attached), but it dosen't work in Positron (Image with dark background), although the setup is exactly the same (same bib-file, same working directory, same .qmd-file etc.). I then tried using the zotero library just to check the functionality, and that worked. So there's either a problem with the VS Code App and bib-files or I am doing something wrong.

Would be very greatful for advice!

Thank you!

Update: Just realised I may be in the wrong repository. Maybe @cscheid (who has helped me out before) could help here again. Thanks!)

Reproduce the issue in the Visual Editor using a .qmd file with a bibliography entry in its YAML header and an exported .bib file, then compare citation insertion with the working Zotero setup and RStudio behavior. Done means citations from the .bib file appear in the Insert Citation window and can be inserted into the document.
