Hello,
It seems that the switch is configured - and it is probable that its line con 0 is configured with the no exec command which would disable the command interpreter. This is a common typo when trying to disable automatic logging out - instead of no exec-timeout, people configure no exec and lock themselves out.
I suspect that this is what happened. The easiest way out of this would be to perform the password recovery procedure. Please follow the instructions in this document:
Please let us know if you were able to recover your switch this way!
Best regards,
Peter

Hello dear
Flash image usually gets corrupted especially when you have electricity disruption, try below as I tried for Catalyst 3550
