Short description of error
When you use operation «CCN ressurect circle center» addon produces circle polyline with two points on the same place. It prevents to move origin to the center, when you use «Origin to selected» in the cursor or median mode and it can produce zero polygons when you extrude.

Minimal steps to re-create:

  1. Edit, Preferences, Add-ons, enable "Mesh: tinyCAD Mesh Tools"
  2. File, New, General
  3. Delete cube
  4. Set view (7): Top Orthographic
  5. Add, Mesh, Circle
  6. Edit Mode
  7. Move selected (all points of the circle), x=1, y=-1
  8. Clear selected, then select 3 adjacent verts (I choose South East)
  9. Right click, TinyCAD, CCEN
  10. Select "num verts" to be 8
  11. (Screenshot) New_circle_creation.png
  12. Deslect points, then select 1 of new 8 points
  13. Select linked: Ctrl l
  14. (Screenshot) 8point_circle_with_9_verts.png
  15. Observe the points selected "median point" is not in the centre.

Inspect source code at:
https://projects.blender.org/blender/blender-addons/blame/branch/main/mesh_tiny_cad/CCEN.py

Line 28:

for i in range(num_verts + 1):

The "+1" causes the created circle to overlap the first and last points generated. This has been the case forever.

Changing it to be:

for i in range(num_verts):

The number of points in the generated circle is now correct and the median is now in the centre.
Here is a screenshot demonstrating the fix:
