Please note my post is meant with a kind heart to help you. I can't tell if the quilt will fall apart from the quilting but I do see some issues. You didn't mention your techniques or experience with quilting these types of projects so that may also be a factor also.
I am seeing inconsistent stitches. Some are longer and then some are shorter. On the next to last picture, there are cross-over stitches- a lot of them. The corner of binding has a wrinkle and the corner is not a true 45 degree corner. There is another lose thread thread on the binding and two rows for a few stitches. Did you start and stop when stitching that corner? I don't think the quilt was squared correctly looking at that binding corner.
I wish you the very best solution for the issues. Learn and grow from this experience in your quilting journey.
