@lucas-28 Thanks for discovering and reporting!

What is causing this is that the tire selected in File A uses filament number 7. The crash happens when that is pasted into File B, which only has 4 filaments in the configuration. Studio tries to assign "filament 7" to the pasted part, but that filament doesn't exist.

Lucas, if you need a workaround, before copying that tire from the first file, change its filament to a lower number, like 4 (which should also match the TPU filament in File B).
