It keeps crashing

This use to be my favorite app but the only problem now is that I cant use the zoom in 2-D top view when I try the app crashes but Im glad the old builds are back also it would be awesome if you could choose the background color which is normally white but that makes it to where its hard to distinguish between white wool and the background so if we could make it to where the background could be toggled from black or white that would be amazing
