That's bad, and probably the source of your issue. there should be a flapper that opens and closes in there when you try to dispense ice. Normally closed. That is the source of the problem then. If you can pull the dispenser board off behind it is a solenoid that opens and closes the flapper, that probably has failed.
Taking it apart:
Be very careful if you decide to remove that dispenser board assembly, the little plastic tabs that hold it in are often very fragile, look under the bottom lip for releases for it. Might be 2-3 little screwdriver slots, might be a few holes for a small screwdriver to release it. It'll have a few wires connections on it too.
Behind that you'll need to remove the plastic assembly that holds the cup cradle, a few screws and it is out, note the wire positions before you yank it out.
At this point the solenoid will be visible. You might be able to move it gently or see if the linkage for the flapper is stuck or off. If you can get the flapper closed that'll solve the frost issue, but until it works normally no ice is gonna come through that door.
Don't be surprised to see mold or mildew up in there, if it has been wet and warm for a while it can be kinda nasty. It is possible that the plunger that moves inside the solenoid is frozen in and can be resurrected, but the solenoid is cheap and pretty easy to replace, might be worth getting one to have on hand so you don't need to take it apart twice. You can get one here and always return it if not needed.
Also inspect the flapper itself, if the rubber part is distorted, cracked or in anyway damaged, replace it too... that flapper is also cheap and a source or warm air intrusion that'll frost up that chute.
