Using blender 2.90.1 i'm trying to make a knot using a bezier curve. Suddenly I can no longer edit my bezier curve. In edit mode the handles are not shown (see screenshot). My overlays are turned on and I restarted blender multiple times without a succes. I also tried copy pasting in a new blender file but this also didn't help.
Can someone please tell me what I'm doing wrong?
