Dialouge prevents the game from resuming, in addition GPU spikes to 100% use

Just as the title describes, I was in my first winter cycle, than suddenly i get a notification that a neighboring hostile country(?) is "incoming".
the dialogue there works fine and the game is progressing, all of a sudden when they finally arrive and they need to start their dialogue the screen dims and nothing, this continues indefinitely no matter how long I wait, it forces me to exit the game and try to load it again in hopes it will progress but nothing.
in addition the menu works just fine when I press escape but the only options I have are "resume/options/exit"
I have no mods what so ever, here is how it looks and the game saveGamesave:
