  • $\begingroup$ you appear to have two parallel edges at the crease point, possibly duplicate vertices as well. Try selecting all and merging by distance and also removing the extra edges. $\endgroup$ Jan 26, 2022 at 16:33

As you can see in the following image (1), you have Normals pointing the wrong way. Blue facing out and red facing in. To fix this, Select All and press Shift+N to Recalculate Normals. You can also go to Mesh > Normals > Recalculate Outside ( Alt+N ). (2) Once Normals are recalculated to point in the same direction, the creases will be fixed.

Side tip : To visualize Normals like in the image. Check Face Orientation in the Viewport Overlays menu. (3)
