So I just updated the game, and I'm having this issue where the game will just cease working when I try to go from VAB to the launchpad. The 'save', 'load', etc buttons in the top right will fade to become non-clickable, and the game will cease letting me access the esc menu. On top of this, I can still navigate the parts in VAB, as well as see the kerbals doing their thing in the background. I cannot however, interact with the ship I've built. Is this a known issue, and is there a fix for it?
