Photos stuck in iCloud folder during Windows 11 sync, unable to retrieve

And so, I have an iPhone and a Windows 11 computer, I wanted to upload my photos from my computer to icloud in order for them to appear on my iPhone, from the beginning I tried to upload my photos from my computer to icloud via the icloud website, but icloud does not allow this because the photos are not in jpeg format is not discounted in icloud. So I decided to download icloud for my computer, I downloaded it and synced my photos with the explorer app. After that, I selected all my photos on my PC and dragged them to the icloud folder, and they didn't sync anymore, and they were signed as delayed in the folder, they disappeared from the original folder, and I can't pull these photos out of the icloud folder, it just showed me an error every time I tried to copy my photos. from the icloud folder back. As a result, all my 2 thousand photos that I added have disappeared, I am very disappointed because there were photos of loved ones and the memory of them. I would like you, Apple, to add to the user manual, because it says practically nothing.

This means that if you add photos to the icloud folder on your windows, then be sure to copy the photos, rather than dragging them from the folder, because they can get stuck in the icloud folder during endless synchronization and disappear forever. For a stupid reason, I did not create an archive with these photos so that they would be stored in 2 places, but relied on apple and their icloud. Don't repeat my mistakes, and before doing anything with the files you need, create an archive so that they are in 2 places before doing anything with them.
