You have quit following through after release like you used to. The symptoms that you describe are classic to an archer who is ending the shot when they let go and not when they complete their following through.
You have to stay with the shot at least until the arrow is away from the bow. It doesn't take much to do this since the arrow is moving pretty fast.
Part of it is in how you set up the shot, both mentally and physically. Right now you are setting up to finish at let-go. Being human, you begin finishing a tiny bit before let-go which leads to creeping, collapsing and plucking.
Some find it helpful to pick a spot on their shoulder or neck and that is the "conclusion" to their shot. They set up
(both mentally and physically) to stay with the shot until their hand hits that spot.
The others are right about the bale being the quickest way to work this out. But be sure to gradually work back to full distance when you have a good subconscious follow through. Immediately jumping back to full distance usually leads to other problems.
Hope this helps,
