The problem with the quest "Better to stop!" (Fallout 76)

people hello, we need your help. I play In Fallout 76 and faced a problem in the quest "Better to pass" after collected blood, found a T-shaped fuse, putting blood in a centrifuge and a fuse in their seats, in the terminal constantly writes that "the required blood sample is not loaded into the centrifuge." Maybe how to restart the quest or how to solve this problem?
