--Solve:

Account: Local account with blank password only allows console login ", double-click to open and change to" disabled ".

Click "Retry" to normal.

If you also have DBCA or NETCA errors, you can skip them all first, and then use command NETCA or DBCA alone for listening configuration and database creation.
The key is to look at the log information generated, to find out the specific cause of the error based on the log content, in order to locate the problem and resolve the problem well.
