Locking / Locking / Locking the driver’s door blocked – door cannot be closed

Good morning, especially today in the “snow-driving” the following problem occurs at our Agila A: With the FB the door was opened normally. After that, however, the door could not be closed: The bar or hook in the door no longer snaps back, remains firmly in the locking position. That is, when trying to close the door, the handle/lock bar attached to the B-Holm pushes against the lock/hook of the door lock or door lock and d He no longer snaps back into the “open” position. The door no longer closes. Instead, it swings up and thanks to the snowfall outside, it snows the interior. The interior lighting therefore stays on. The hook/bar in door lock mechanism sits bomb-proof and can not be caught back by force – with the other doors this works quite simply, slightly against it push and the bar/hook snaps back. I have now first the door from the inside with a cord tied, so that not too much snow blows in, and the battery clamped (because of the interior lighting), but that is not a solution. It is also striking that since then the FB of the key no longer functions – neither on nor on. The central locking as such, however, still works, i.e. both by turning the key in the lock as well as by the locking button in the driver’s door, the locking mechanism of all locks can be triggered. That the locking bar/snapper/hook of lock mechanics of the driver’s door remains in the “closed” position and is blocked. Outside it snows, it is cold, my ability and willingness to expand on mere suspicion the door panel and to try to understand the mechanics (if at all accessible) is therefore extremely limited. And since Sunday is also no workshop open. Does any of you know what is the cause and how I can fix it?
