Thanks for the info, this could be helpful in solving the issue.Hi,
I ran into this as well , although, I ran the game as administrator, in full screen (I was playing windowed), and then the skip arrow showed up white, and I could click it.
Before it was a pale-blue unclickable button, and the puzzle pieces froze as you described.
I thank the Dev for the skip button. I tried to do the puzzle (easy as it was), but it always froze on me.
