I can work with cmd normally with sql.
I can authenticate with sqlplus to my database with oracle.
Following command works with cmd sqlplus / as sysdba
but not with wsl 2 v18. with command sql

Password? (**********?) ************
Connection failed
  USER          = SYS
  URL           = jdbc:oracle:oci8:@
  Error Message = ORA-12547: TNS:lost contact
  USER          = SYS
  URL           = jdbc:oracle:thin:@127.0.0.1:1521:XE
  Error Message = IO Error: Got minus one from a read call, connect lapse 5 ms., Authentication lapse 0 ms.```

I also tried with same prompt 
Prompt: sqlplus / as sysdba
