[Koha] Patron search not working in 24.05 (Month out of range)

Hi, yesterday I did the upgrade to 24.05 (from 22.11 → 23.05 → 23.11 → 24.05) and I have the "500 - Month out of range" error again in patron search. I already checked the borrowers.date_renewed and set it to NULL, but the search is still not working (https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=32641) I have no errors in intranet-errors.log Any ideas how to solve or at least debug the issue? Thank you! Stephan
