Missing High-Security ACL
It was determined that the High-Security Plugin was activated. To workaround the issue, the ACL that was failing was deactivated. We suggested to reactivate the ACL and import the missing High-Security ACL (sys_security_acl_e0d8a3ffeb3630003623666cd206fe25.xml) into the instance. Confirmed this is now working.
