Gmod crashes, cause is hexed weapon, maybe something else.

I hexed a file, I opened the spawn menu where it is located then it shut down/crashed with an error message, For my bad luck it was in Finnish so you guys can’t read it. Could somebody of you guys help! I hate when that happens if i find a cool model. Please help me. When i removed file, didn’t crash when i opened the location in game, where the model was.

My Finn friends say it’s a memoryleak or something on the goddamn Gmod or PC.

It’s the model. I had this recently just trying to fix a model with the wrong textures. Had to redownload the pack it was in and then recompile the model.
