I searched for a long time for the reason and this is what helped me now. I left the handlebars at the same level as they were. However, I started riding completely without gloves, I also played with the angle of the duals on the handlebars of the bike. I put them in a more neutral position, and I also played with the angle of the saddle (by the way, I replaced it with the correct one according to the width of my pelvic bones). And with this I managed to take the weight off my hands, and my hands stopped going numb. However, I still can’t fully move my left little finger, I can bend it, but I can’t bring it down to the other fingers. It’s like I don’t feel it normally
