Oh my, that's a scary looking board state. 🥶 But yeah, I'll keep investigating, seems like it has something to do with being high level (or at least having loads of skills). Yeah I bet it's stuck on the level up menu before somehow without showing the skill picks. Pause/quit and tooltips are working so it's not fully frozen but just waiting for the skill to be picked which you obviously can't do cause they aren't shown.
