[Koha] Software error: Invalid data

[Myriam Torres]

Hello Koha Community,
We are getting this error message when we try to get the information of our
books, we started to get this error after the last update. Do you know how
can we solve this problem?

Software error:
Invalid data, cannot decode object (id=16023, format=marcxml,
schema=MARC21, MARCXML error=':9: parser error : PCDATA invalid Char value

                          ^')

Thanks in advance
