Game freezes when pressing ESC while quick-saving

There seems to be a game freezing bug when you press ESC very quickly after quick-saving. Instead of the pause menu, there is just a small modal with the text ‘PAUSED’. The game doesn’t crash, it is just stuck in a paused state where no button can resume the game. Pressing the number keys still shows the weapons changing on the HUD. I have been able to reproduce this bug every time.

Game version: 1.0
