No.  Yes, it was exactly the same error message, but the actual
message is this:

  Warning (emacs): Emacs reader failed to read data in
  "/home/nlj/.cache/org-persist/gc-lock.eld". The error was: "End of
  file during parsing"

It comes from the error handler for the condition-case in
org-persist--read-elisp-file.

(To be absolutely clear, the changes I applied to my Emacs are the
ones I showed in my earlier post[1].  This only applies the atomic
write part of your patches, not the "write index before writing
cache data" part (which I didn't see how to easily integrate into
the org-persist.el in Emacs 30).)
