If you have made export using FULL=y CONTENT=metadata_only from 19.3 db version, it is unable to import dump in 19.9 the cause of an error is ORA-02376: invalid or redundant resource.

If you search ORA-02376 on MOS you can find «DataPump Import Fails With Duplicated Resources In The Create Profile Statement (Doc ID 557383.1)», but this is not our case. The root of the problem is user profile which has PASSWORD_ROLLOVER_TIME option introduced from 19.12 according to Gradual Database Password Rollover. Creating profile with PASSWORD_ROLLOVER_TIME option produces an error ORA-02376 on db version lower than 19.12. I tested only 19.9. Export from 19.12 version and higher with parameter version=19.9, or 19.0, or 12.0 didn’t help.

You must skip profile from export and make it manually.
