Is org-fc-awk--find among them?

Yes. It is. It's defined in org-fc-awk.el

I'm not sure if howm is the issue then. C-h f should show some functions starting with org-fc-awk-...,

Yes, it is showing up.

Yes it gives an error message:

*** Eval error *** Symbol’s function definition is void: org-fc-awk--find

Should I create a new issue because it is being tested on GNU/Linux now, but I use howm emacs package to store files with flashcards ?

Are you seeing any error messages or did it just stop working?

Sorry, for the late response and incorrect report in the first place.

Yes, I saw error messages. org-fc-dashboards is working although it shows zero cards and when I tried to execute org-fc-review-all it returns "No cards due to riview".

It is not working even on GNU/Linux. Should I submit new issue about interconnecting howm and org-fc ?

Suddenly it's all stopped working again. Either No cards due to review or *.tsv file not found

I am sorry. I subscribed to org mode mailing list and have been told there that by removing escaping I can get vulnerability. Also problems with shell-quote-argument highly likely have been caused by myself setting shell-file-name to pwsh.exe I will remove this setting from my config and go back to having shell-quote-argument in org-fc functions.

I now have access to a windows computer and once I have set up Emacs, I can try to reproduce these bugs.

The most easier way to setup emacs on windows is typing winget install GNU.EMacs

But there is also emacs in scoop (scoop.sh), which i used for installing busybox and other commandline apps, that can be called from terminal. It solves wingets problem with finding program in PATH.

Regarding the error message you're seeing, something similar seems to happen in the org-fc-cache-hashes function when it's used with directories that contain no flashcards. In your case, there are probably some of these in your org-fc-directories list.

Probably, there are some. But I can review cards without this error, when executing org-fc-review in *Messages* buffer instead of opened org buffer with flashcards.

The error that I get in Messages sometimes:

(:path "-" :cards (
  )  :title nil)

I think I made it work. Now I can run org-fc-dashboard and it seems to me that org-fc finally can find my cards. I also reviewed all my cards two times on windows.

Here is parts my config where I changed org-fc functions: https://github.com/artsi0m/emacs-organizer/tree/da2ce20a146738aec75592e17148f695e017b7bb?tab=readme-ov-file#try-to-use-busybox-from-scoop

Sometimes error with find and short sexpr would appear in Messages, but I cannot reproduce it now and everything seems to be working.
