contents	The results of the search for the $e^+e^-\toη^{\prime}γ$ process in the center-of-mass energy range from 1.075 to 2 GeV are presented. We analyze data with an integral luminosity of 746 pb$^{-1}$ accumulated with the SND detector at the $e^+e^-$ collider VEPP-2000 in 2010--2024. The $η^{\prime}\toηπ^0π^0$ decay is used in the analysis, with the subsequent $η$ and $π^0$ decays into $γγ$. Upper limits not exceeding 13 pb have been set on the $e^+e^-\toη^{\prime}γ$ cross section at the 90\% confidence level.
