[Koha] 404 Error after upgrading to 25.04

Hi After Upgrading to 25.04 I get a strange error: Selecting an entry in a list of results the record is displayed but a small window pops up on top oft he record displayed: Something went wrong when loading the table. 404: Not Found. But I can work on the record and there is no other problem. This happens only in the staff interface. The opac is not affected. Greetings Beda
