We report cross-section measurements of the final-state muon kinematics for *n&sub(*m) charged-current interactions in the NOvA near detector using an accumulated 8.09×10*2*0 protons on target in the NuMI beam. We present the results as a double-differential cross section in the observed outgoing muon energy and angle, as well as single-differential cross sections in the derived neutrino energy, 𝐸&sub(*n), and square of the four-momentum transfer, 𝑄*2. We compare the results to inclusive cross-section predictions from various neutrino event generators via *c*2 calculations using a covariance matrix that accounts for bin-to-bin correlations of systematic uncertainties. These comparisons show a clear discrepancy between the data and each of the tested predictions at forward muon angle and low 𝑄*2, indicating a missing suppression of the cross section in current neutrino-nucleus scattering models
