What could be the reason for this invalid objects after trying to upgrade?

We recently wanted to upgrade our Database but didnt get to do it as we got a lot of Audit specific invalid objects, after looking online for ressources we couldnt find anything specific reason for this happening

This ones are currently Invalid:

SYS DBA_FGA_AUDIT_TRAIL VIEWPUBLIC  DBA_FGA_AUDIT_TRAIL SYNONYMSYS CDB_FGA_AUDIT_TRAIL VIEWPUBLIC  CDB_FGA_AUDIT_TRAIL SYNONYMSYS DBA_COMMON_AUDIT_TRAIL  VIEWPUBLIC  DBA_COMMON_AUDIT_TRAIL  SYNONYMSYS CDB_COMMON_AUDIT_TRAIL  VIEWPUBLIC  CDB_COMMON_AUDIT_TRAIL  SYNONYMSYS FGA_LOG$FOR_EXPORT  VIEWSYS DBMS_AUDIT_UTIL PACKAGEPUBLIC  DBMS_AUDIT_UTIL SYNONYMSYS DBMS_AUDIT_UTIL PACKAGE BODY

I already tried recompiling them utlrp also didnt work.
