We apply an intense infrared laser pulse in order to perturb the electronic and vibrational states three-dimensional charge density wave material 1$T$-VSe$_2$. Ultrafast snapshots of light-induced hot carrier dynamics non-equilibrium quasiparticle spectral function are collected using time- angle-resolved photoemission spectroscopy. The temperature time-dependent self-energy extracted from function, revealing that incoherent electron-phonon interactions heat lattice above critical on a timescale $(200 \pm 40)$~fs. Density functional perturbation theory calculations establish presence carriers alters overall phonon dispersion quenches efficient low-energy acoustic scattering channels, which results new quasi-equilibrium state is experimentally observed.
