Check OPatch Utility version and Update OPatch Utility:

[oracle@orakldba OPatch]$ ./opatch version
OPatch Version: 12.2.0.1.44

OPatch succeeded.
[oracle@orakldba OPatch]$
[oracle@orakldba OPatch]$


Here we can see the current OPatch version is 12.2.0.1.44. You must use the OPatch utility version 12.2.0.1.45 or later to apply this patch. Oracle recommends that you use the latest released OPatch 12.2.0.1.xx version for DB 19.0.0.0.0, which is available for download from My Oracle Support patch 6880880 by selecting "OPatch for DB 19.0.0.0.0" from the Select a Release dropdown and also select the "Platform or Language".
