"The library has been modified by another program"

@evkamat I created this github issue for you: Broken Backups - possibly caused by terminating frozen JabRef · Issue #10026 · JabRef/jabref · GitHub Would be great to hear your feedback, once you tried the development version.

Thanks to the developers of JabRef!
(…gratitude is never enough for this nice free app:
long-life to open-source initiatives! : )

I still get the problem with JabRef 5.12.

My JabRef settings:
JabRef 5.12–2023-12-24–4233bad
Windows 11 10.0 amd64
Java 21.0.1
JavaFX 21.0.1+6

@GianlucaBaldassarre Please test again with 5.13 We improved this
