Game crashes when I try to switch saber models

Hello! I recently downloaded the Qosmetics mod along with several custom saber models. Everything was working fine at first and I chose a model to test. However, when I tried to select a different model, the game crashed. The game now crashes when I try to select any custom saber model no matter which one I try. Is there anything I can do to fix this? I was really looking forward to using this mod. Thanks!
