I've just updated to 'Org mode version 9.5.4 (release_9.5.4-706-g4702a7 @ 
/home/boudiccas/git/org-mode/lisp/)' and I'm getting this error report from 
org-fold-core (I think) -

I've attempted to run bug-hunter-file against it, and its says that there are 
no problems with it, so I'm puzzled as to what's going on?

Is it a bug against org-fold-core, or something in my file, please?    

Thanks
    Sharon.
