Coping these two surface to a new Rhino file can indeed reproduce the issue you mentionsed, but I’m unable to replicates this issue in Rhino by assigning material to a trimmed surface. Could you hlep recordd a video showing the process of how you assing material to a trimmed surface to trigger this error? Thank you.

at a guess, you should probably run shrinktrimmedsrf after trimming, see if that helps.
