This Letter reports a search for charge-parity ( $C P$ ) symmetry violating nonstandard interactions (NSI) of neutrinos with matter using the NOvA Experiment, and examines their effects on the determination of the standard oscillation parameters. Data from $ν_{μ} ({\bar{ν}}_{μ}) \to ν_{μ} ({\bar{ν}}_{μ})$ and $ν_{μ} ({\bar{ν}}_{μ}) \to ν_{e} ({\bar{ν}}_{e})$ oscillation channels are used to measure the effect of the NSI parameters $ϵ_{e μ}$ and $ϵ_{e τ}$ . With 90% CL the magnitudes of the NSI couplings are constrained to be $| ϵ_{e μ} | ≲ 0.3$ and $| ϵ_{e τ} | ≲ 0.4$ . A degeneracy at $| ϵ_{e τ} | \approx 1.8$ is reported, and we observe that the presence of NSI limits sensitivity to the standard $C P$ phase $δ_{C P}$ .
