For me I have gotten this kind of crash:

And to be fair, I do not know what the problem is. To give a small context when it shows up, so on my scene, I grab a object(a wall). Grab it’s transform, pressing alt + middle mouse click to move the transform as close to the object’s edge. And when I see there is like no space or tiny space away from the edge, while still holding alt + middle mouse button, I press V to snap the transform to the edge. But when I press V, the scene starts to slow extremly much and then the crash happens. And this is exactly the message that I get when doing that every time. But the weird thing is that there is some times, when I do exactly like that, the crash won’t happen. So, if anyone who do read this and do find the problem, is there a way for me to fix the problem from my end?
