Sometimes links with specific filenames do not work

So I've noticed a strange issue where sometimes the hover popup just won't happen with particular filenames. It appears as though some kind of bug happens where a particular filename will get "stuck" somewhere, and then that specific name just stops working.
So for instance, if you change a single letter anywhere in the filename, it suddenly works again. Unfortunately, changing it back does not fix the issue.
For some details on my environment and what I'm doing, I am using Windows 10, and I've been making "hover links" to markdown files. Basically my notes folder is just .md files, so when I put the relative path in to a comment, you get a hover popup:
#? notes/mymarkdownnote.md
If it stops working then simply changing one letter will make it turn back on:
#? notes/mymarkdownnotb.md
I have tested this numerous times - I'd be willing to send you pictures from inside VS Code if you'd like.
Love the extension btw! glad to help if I can.
