Hello, hello, I was in a raid and a character lost in dice and I accidentally passed him the item and he doesn't want to give it back to me when I talk to him, he said, why do we take him out of the raid because he lost the dice, he wouldn't pass the item. I tell him I have tests and he doesn't want to take them.I have a photo of part of the conversation, the dagger is [Tarasca spike. I only want the dagger because the person I won is asking for it

You won't receive the item from Staff.
Since he didn't steal anything, you made a mistake, I'm not sure it's even reportable. On the other hand, the person who should have got the item can report you for not giving them the loot they won, accident or not, assuming they collected all the required evidence.
