Olympus Infinity AF-1 does not roll the film

Hello everyone! I don't know which section to write my question in, maybe someone will help here.
Help me figure out the problem, maybe I don't understand something, since this problem is already with the second camera. I have an Olympus AF-1 that I shot with for about six months, and then after it lay on the shelf for a while, it stopped charging the film. This happens like this: I insert the film, close the lid, and the camera immediately reels off the film. I bought a second camera and found the same problem with it. I recorded a video of how this happens (I pressed all the limit switches so that the camera would work with the lid open for clarity)

Welcome to Photrio.
I moved your thread to the camera repair sub-forum, as that is a slightly better fit. And I tweaked your thread title.
From the video, it appears that the camera isn't "grabbing" the leader when the film is placed where it appears that the film end is supposed to be placed.
In case you don't have it, here is a link to the manual on the Butkus website: https://butkus.org/chinon/olympus/olympus_af-1/olympus_af-1.htm
The donation requested on that site is very reasonable.

Yes, I've read this manual, but I don't understand what I'm doing wrong. It seems that after closing the lid, the camera first rewinds the film back into the cassette and then rotates the receiving spool.

I just realized that you are trying to load film that is cut straight across at the end. When that camera was new, film wasn't available that way. Try it with the film cut with a loading tongue instead.
Something like this image from the manual:

It still isn't; Fomapan 400 as shown in the videos of @Earl_matveev comes with a half-width leader just like all other film.

@Earl_matveev try cutting a normal 35mm leader to it an then check again if the problem persists.

It's an interesting assumption, but nothing changes.

I had been shooting with this camera for a while before and everything worked perfectly, but then the camera lay on the shelf for a while and this problem came out.
