Unable to Snap to Grid

Hello Andrew and Maximus, you’ll notice in the video tutorial after you create a cube exactly as he shows, he tells you to press Ctrl + End to align the cube to the grid, basically along the bounding lines (yellow lines) of the brush shown, when you look at the video you will notice the cube in fact moves. When I do it, the cube doesn’t move, no matter what position of the cube along any axis, and it creates an Undo, which of course clicking the Undo does nothing either. Snapping is turned on and I know it’s not a toggle. Of course pressing End Key by itself will drop a mesh to the floor I am trying to create. It’s not the biggest of issues, and it doesn’t stop me from positioning things manually and adjusting the Position Grid Snap Value, the problem would be that if someone that’s not experienced with this comes across this as well in the first set of tutorials, might be a bit stuck trying to figure it out. Were the Hotkey’s for it changed?
I’ve also ruled out the keyboard keys sticking because the keys aren’t stuck and I can type normally lol.
