Deadlift back pain

[Neovictor]

This is a common question that has been answered in so many places, but I've read and watched so many videos and I still have back pain when deadlifting. The pain is very bad to the point that I can't do another rep because of it, but I know that I can because I don't feel fatigued yet. So, the back pain is impeding me from performing more reps and I want to fix that. (I feel the pain in the lumbar area)

Obviously, nobody will know what's wrong if you don't post a form check video, but listen to alan thrall's advice in this link and switch to rdl's for a bit:

I will add if it's in the lumbars it's better than being in the low back spine area.
Do you wear a belt?

Two points:

1/ Does it hurt when you're lifting less weight?

2/ Regardless of how you got to this point; when you've taken the slack out of the bar and you're about to lift, what do you do, what moves first?
