Behind the back appeared a crossbow like Nepis (The Witcher 3: Wild Hunt)

Shta?

That is, listening to the dialogue and watching the cutscene is not destiny? Vesemir gives it to you, says that he played it at cards. And to use ... probably a radial menu with signs is also not destiny to open and open your eyes.

That's it. At least I looked at the training.

Look in your inventory, you have it there in a specially designated cell, you can remove it ... although it is extremely useful with flying opponents, and under water it is your only weapon. How to use is written above.

PS / Then these characters rivet big posts, like: 101 reasons why you shouldn't play The Witcher 3, why the game is shit, etc.

Nobody understood what it was about, apparently.
So, there is such a bug: during the first plot transition on Skellig, an NPC crossbow appears behind Geralt's back (for example, such as that of Vernon Roche). And instead of a sword in the cutscene, Geralt hits the pirates with this crossbow. The treatment is as follows: you need to sleep with any girl, in any of the brothels.

Well, that's how it was necessary to write, otherwise it is not clear. For example, I haven't been to Skeliga yet, so I don't know that such a bug exists.

A crossbow appeared behind his back like a non-writing.
Well, these words lead to certain thoughts, it is already clear that this is not about an ordinary crossbow. And I myself have met such a bug, so I know what needs to be done to get rid of it.

Does Vychuchol
hit hard ? Or is it just texture and damage and animation from equipped sword?

Vychuchol
"NPC" in his dialect, this is most likely an NPC; DDD

only in the cutscene, the rest of the time the crossbow hangs aimlessly behind the GG's back.

Vychuchol ".. It is treated like this: you need to sleep with any girl, in any of the brothels ..."
not only - you can also "fistfight". In short, you need the engine itself to force the "section" of Geralt

Exactly, I just wrote one of the options.

Play the game carefully)

it depends on the crossbow and the level of the monsters and the monsters themselves.
