Studio crashes after inserting SurfaceAppearance into a Part

[00snotty (snotty)]

Whenever I insert SurfaceAppearance into a part by accident, the studio crashes. Right before the studio crashes, I get a warning that says that SurfaceAppearances can only be inserted into MeshParts

I know putting a SurfaceAppearance into a normal part doesn’t work, but I sometimes put in there by accident and it’s really annoying that my studio crashes everytime I do make that mistake.

My device specifications:
OS: Windows 11
RAM: 32GB DDR4 3200MHz
GPU: NVIDIA GeForce RTX 3070
CPU: Intel i7-11700K

Expected behavior

I expect my studio not crashing after putting a SurfaceAppearance on a part
