Bisecting, commit 1c0f374ec3 was identified as the one causing the crash. However, upon closer examination, it is not clear why the loop cut code would lead to a crash.

Ciao Germano, mi piacerebbe aiutare di piu' blender, sono un programmatore ma mi trovo molto disorientato con il codice di blender, avrei bisogno di qualche tutorial per capire le basi e piano piano fare qualcosa di utile, mi potresti aiutare?
