Short description of error
Blender closes sometimes when you press Ctrl + Z
Exact steps for others to reproduce the error
The problem occurred when I was extruding an edge and needed to give Ctrl + Z and other times I was moving edges and vertex and needed to press Ctrl + Z.
I have not identified a pattern for the problem to occur, sometimes it stays open for several minutes and I use the shortcut several times without problems.
