When I tried adding this engine in Cute Chess (https://github.com/cutechess/cutechess), the program throws an error indicating that it was unable to get some configurations from the engine!
I'm afraid more information would be required to diagnose this particular issue.
It is known that many users are able to make Ceres work with CuteChess, for example when she is playing in broadcast tournaments.
