Holding Shift while moving vertices in CollisionPolygon2D crashes Godot

Issue description

Essentially, I was working on the collision for the player, and used a CollisionPolygon2D. I was going to add a new vertex and drag it along, but I wanted it to not snap to pixels so I hit alt and shift and different buttons to figure out if one of them disables snap.

Essentially, hitting shift while adding a vertex in polygon crashes.

Steps to reproduce

1. Create a 2D scene and a KinematicBody2D
2. Create a CollisionShape2D as a child of KinematicBody2D, and have it be any shape. (edit: some shapes seem to work and others not for some reason. Circle doesn't work as far as I've tried.)
3. Create a CollisionPolygon2D as a child of KinematicBody2D, and start adding vertices.
4. Add a vertex between two vertices but do not release the left click. Start holding shift right after.
5. Move around the vertex and it usually ends up crashing.

Minimal reproduction project

GD3.5-Reproduction has the reproduction scene I have for this issue: GD3.5-Reproduction.zip

GD-TowerGame is what I was working on when the issue occurred, located in res://Objects/Player.tscn GD-TowerGame.zip

Out of curiosity, can you reproduce this in 3.4.x?

I reproduced it in 3.4.5 and fresh master build, 100% reliably including a circle CollisionShape2d.

Edit: It seems it only happens on the very first move of a newly created vertex, as soon as you stop pressing left click then it doesn't reproduce.
