Thanks, Jean,

This is what’s in ~.config/fontconfig/fonts.conf:

 

That definitely does not look like a valid config file. It has a duplicate XML declaration, and the <dir> element should not be empty. Not sure what software left this borked config file on this computer.

I would just remove it, it's not doing anything apart from triggering errors AFAICS.

The lead-sheets deliver the same “Fontconfig…” error messages, but also include the following warnings: interpreting music...
warning: cannot find property type-check for `markFormatter' (translation-type?). perhaps a typing error?
warning: skipping assignment

You should always (yes, always) run convert-ly before trying old scores on new versions. It will automatically fix the syntax of your file to be compatible with the new version of LilyPond. Developers (like me) put awful amounts of efforts into making it work well. It's a pity not to use that. In Frescobaldi, that's in Tools > Update with convert-ly.

I’ve tried that on these old files, but it doesn’t resolve the problem.

Are you sure that the 2.23.5 → 2.23.6 conversion step was run properly?

My guess is that you updated the \version number before running convert-ly. It detects the version to upgrade from using the version statement, so you should not do that, but instead let convert-ly change the version for you.

In the log from convert-ly that Frescobaldi shows you, you should see "2.23.6" among the list of conversions that were run.

Another possibility is that you have a use of “markFormatter” in an include file and you forgot to convert that one.
