Window Size bug

flme08

2 days ago my game decided it would open in a tiny window like in the picture, the game is running and I can hear the music but its like someone made the window so small I can't do anything. Anyone else had this problem and anyone know how to fix it? It's driving me crazy.

See the line in my signature ▼ down there about Subnautica running in a tiny window for a fix.
