[Koha] unable to import bibliographic and authority records.

We've updated to Koha version 24.0516 and are unable to import bibliographic and authority records. We're using UTF-8 encoding, but we've tried other standards, such as XML, and they don't work either. Any feedback would be greatly appreciated. Lic.
