"ORA-28374: typed master key not found in wallet" During Wallet creation on 12.2.0.1.0

Hi,
we had old wallet with lost password.

Encrypted tablespaces were dropped as it was described here https://support.oracle.com/knowledge/Oracle%20Database%20Products/757936_1.html (Creating Encrypted Tablespace in 11.1 DB Fails Ora-28374: Typed Master Key Not Found In Wallet (Doc ID 757936.1) Last updated on FEBRUARY 04, 2020):

SQL> SELECT tablespace_name, encrypted FROM dba_tablespaces;

TABLESPACE_NAME                ENC

------------------------------ ---

SYSTEM                         NO

SYSAUX                         NO

UNDOTBS1                       NO

TEMP                           NO

USERS                          NO

and when I try to:

SQL> ALTER SYSTEM SET ENCRYPTION KEY IDENTIFIED BY "password";

ERROR at line 1:

ORA-28374: typed master key not found in wallet
