I have a minimal org-roam configuration in a Doom Emacs environment. It was enabled with the +roam flag for the org package in init.el.
Aside from that, I have merely pointed the directory to the appropriate location (where I have used it before for about ten notes now). Suddenly I was getting a “Skipping file unreadable while building cache” and have not been able to use org-roam since.
I have posted my configuration below, but it just has the bare minimum.
Solved: It was an issue with vterm. I simply deleted it for now, just have to wait for a new release.
