Artifacts in translucency reflections

Hello everyone! Please tell me how to get rid of artifacts on glass reflections in UE5. Using A Ray Traced the translucency. There is no such thing in the Transparency of the raster, the path tracer does not have such a thing. The grid of the model is good, high-quality. The problem appears when the size of the Source Radius or Soft Source is changed. Artifacts only have reflections from light sources. Please help me!
