Hi! Thanks for the report.

Any chance something is up in Vertico? Or with your config?

From what I can see, inserting previous historical entries during 
project file completion (with 'M-n') seems to work fine both when using 
the default completion UI, and with Counsel (which is what my current 
session is equipped with).

I also tried replacing the latter with 'M-x vertico-mode' just now, and 
'M-n' seemed to work fine there, suggesting the files visited previously 
with the same command. Tested in both Emacs 29 and 30.
