An issue with the camera

I tried to create a spring arm but I think I failed and then when I deleted it, this just happens. (In the videos) I tried to google it and everything but I didn’t find a single answer related to it. Can anybody help me? (DM for blueprint or settings if needed) Also before was the first person camera like attached to the body, so like the idle and running was connected to the body and all help is appreciated, because it’s my first job.
