  With the aim of interpreting anomalous lensing events with no suggested
models, we conducted a project of reinvestigating microlensing data in and
before the 2019 season. In this work, we report a multi-planet system
OGLE-2019-BLG-0468L found from the project. The light curve of the lensing
event OGLE-2019-BLG-0468, which consists of three distinctive anomaly features,
could not be explained by the usual binary-lens or binary-source
interpretation. We find a solution explaining all anomaly features with a
triple-lens interpretation, in which the lens is composed of two planets and
their host, making the lens the fourth multi-planet system securely found by
microlensing. The two planets have masses $\sim 3.4~M_{\rm J}$ and $\sim
10.2~M_{\rm J}$, and they are orbiting around a G-type star with a mass $\sim
0.9~M_\odot$ and a distance $\sim 4.4$ kpc. The host of the planets is most
likely responsible for the light of the baseline object, although the
possibility for the host to be a companion to the baseline object cannot be
ruled out.
