ᐅ Patio umbrella does not close

Hello!
We have a typical Northern German problem – the weather is changing and it’s getting stormy here.
During the summer temperatures today, we set up and used our brand-new ( 🙁 ) cantilever umbrella.
Now, in the evening, we wanted to close it, but when turning the crank counterclockwise, the umbrella doesn’t close; instead, the crank handle comes off in our hand.
It unscrews from the thread.
There was a small screw inside, which we tried to screw back in, but when turning counterclockwise again, it just falls out.
This is our first (and probably last) cantilever umbrella. Can anyone give us quick advice on how to close it without the crank, preferably without damaging it?
I couldn’t find any useful information on Google.
If I leave it open, it will probably end up three properties down tomorrow. 🙁

That is probably a small grub screw that prevents the crank from unscrewing backwards out of the thread. There must be a recess somewhere on the shaft where the grub screw fits precisely when inserted. Without looking closely at the crankshaft, place the crank in the only correct position and then tighten the grub screw firmly (don’t overtighten!). Otherwise, take some good photos so we can have a look at the problem.

By the way, I’m still looking for a similar umbrella—do you think it would fly all the way to Münsterland? :p

I just took another look—the small screw is there, and it doesn’t even have a Phillips head. I can even visually reassemble the small parts to fit correctly. The problem is, I can push the small screw into its “thread” with just my finger—without a screwdriver. Unfortunately, it doesn’t hold at all anymore, I’m afraid. So even if we carefully screw it in, since there seems to be no actual thread, it will slip immediately when turned backwards, and then I’m left holding the crank again. The canopy stays open. Is there any way to close such a canopy without the crank?

Could you please upload a picture of it here?

Probably a gearbox that doesn’t rotate backwards on its own (I can’t recall the technical term for it right now...). But a photo would really help; otherwise, we have to guess. 🙄

Working on it – first I had to take the photos, then sync them to my computer. I don’t have the cable handy right now since I usually sync via drive, but because I hadn’t synced for a while, it insisted on uploading two-week-old videos first… 😀
Anyway, here are the pictures and thanks for your help.
I’ve also contacted the seller, but I’m not sure how to return it if I can’t close it properly.
