I had to reset my computer once when that happened.
I remember that ALT+F4 worked well for closing this game.You can also use your Task Manager for it.(Ctrl+Alt+Delete) No need to restart the game really.
As for inventory bug, in most areas you don't really need inventory since you can select weapons via shortcuts.(And use F5 key for quick saves and F8 for quick loads if I remember correctly)
The inventory bug has the chance to disappear when picking up new items so imo it isn't necessary to quit the game unless you really need to access the inventory.
