Archetype machine. Cant execute sql commands

Hello everyone. I try to pawn Archetype machine, but i some stuck (i even see walkgrouth, but this not help).

My problem:

I authorize as 'ARCHETYPE\sql_svc dbo@master' at target machine by impacket use login and pass from ‘prod.dtsConfig’ file.
Try to run EXEC xp_cmdshell 'dir'; (for example and check if i can use xp_cmdshell) and get error. After that (using help command) i enable this functional by exec enable_xp_cmdshell. But now any sql command return empty result for me (just not printed any output) (for example:

SELECT IS_SRVROLEMEMBER('sysadmin');

or

SELECT IS_SRVROLEMEMBER('sysadmin','ARCHETYPE\sql_svc');

or

SELECT IS_SRVROLEMEMBER('sysadmin','ARCHETYPE\sql_svc dbo');

)

Any suggest ?

Thank you in advance for the answers and I apologize for possible mistakes in my English, but I try to write without a translator to practice the language a bit.

This is a bug of some versions of impacket, i download ver 0.9.22 an its works perfectly:
