There is some problem with the perl script compatibility between 18.104.22.168 and newer opatch versions.
Try using a lower opatch version or apply the patch manually instead of using "opatch auto"
There is an internal bug already logged for this issue, but fix cannot be provided as the RDBMS version is 22.214.171.124
