Hi, I have a problem with the render. I would like to ask why when I render a sequence, the character is missing in the resulting video format? the environment and the movement of the camera is correct, but character is missing

I used mixamo Y-bot, (before I used UE Mannequin as well) and there is the same problem. When I rendered my sequence (as avi), there was just environment and camera animation, but character + animation (Y-bot/Mannequin) was missing…
