Your shell prompt doesn't look Tramp affin, there are escape sequences:

The login has worked successfully, despite the escape sequences.

This command has failed. Even no output in the buffer.
I recommend to suppress the escape sequences in your shell prompt, see
the Tramp manual for hints how to do this.
> PS: what's meaning of regex: "[^#$\n]*%s\r?$"?
It's part of the `format' clause to determine the shell prompt; %s is
replaced by the value of `tramp-end-of-output'. In your case, this
variable should be "#$ ". Later on, once the connection has been
established, `tramp-end-of-output' is a random string like
"///e90c02f62ec0d7a2f6da0b67a20f8264#$".
