Help with inner extrude

I keep getting this problem and im not sure how best to fix it?
Any help would be great

the reason are the edgeloops being so close together on your selection. an inner extrude uses the (point) normals to move(scale) your selected polygon patch points. this results in crossed loops and irregular polygons ans shown in your example. there are two workarrounds.

1. cleanup the edeloop defining your selection. make sure the points are somewhat evenly distributed. however this method has its limits.

2. for (almost) planar selections - leave the mesh at it is, inner extrude the selection by 0 cm and than scale it manually with the axis gizmo. make sure your your modeling axis is set to selected + normals and the the z axis is turned of to prevent any unwanted z scaling.

in your case i would go for option 2, as it is perfectly planar and you have got also a matching (modelling) axis, as shown in your screen.
