This is a Fully Define Sketch because sketch is not moving by pulling the corner. Part file is attached.
It is colour change of the sketch and indication in right corner bottom of screen tell us it is a "Fully Define Sketch".
Here it is easy to find out even though color did not change, because sketch is a simple one. How to find out if sketch is a complex one in a 3D sketch.
I tend to be lazy and avoid extra work.
Virtually all of my 3D sketches (except for routed systems) are generated and controlled from 2D sketch(es).
Tubing, piping, electrical wiring routing through an assembly.
Most assemblies have one or all.
My guess is that the reason nothing moves is because SolidWorks cannot figure all the relations out. Your sketch is still under defined. I can "wiggle" your 3D sketch plane. I just cannot figure out how to lock it down right now.
In theory sketch is under defined but in practice it is fully defined.
Sorry, that is not the case. Under the right conditions, some of the sketch geometry will move (I just cannot find how to prove that).

Hi Maha:
Please delete the 45-degree dimension add Along Z relation for this line to fully define the sketch.
