A signitory yes, but not a party to the conflict. Russia denied being that, and under point 10 they denied having any forces inside Ukraine so could not be asked to withdraw.

Schrödinger's party if you will; not there for any responsibility, there to claim foul play when the other guys refuse to play along with your charade.

At best you could argue that none of the parties adhered to the agreement, but regardless the full scale invasion of a neighbouring country, the rape and wanton murder perpetrated by the VDV/capitalist murder brigades under Prigozhin, the kidnapping and forced relocation of the Ukrainian children in occupied territories and let's not forget threats of all out nuclear war is so far beyond any perceived slight under the Minsk agreement that any reference to it is just comical at this point.
