Linkage issues with the Kangaroo and Wallacei

I would like to ask, I would now like to Kangaroo optimize my mesh, generate a mesh-shell structure from the optimized mesh into Karamaba for structural measurements, and find the optimal mesh length using Wallacei. But the result appears as below, is the calculation too big? I wonder if it’s because Kangaroo hasn’t reached a steady state while optimizing, the data keeps changing and then Wallacei just keeps receiving the changing data and crashes? I would also like to ask is the data that Wallacei receives is the data after Kangaroo is optimized and stabilized or is it the data that has been in the process of changing?
