Over extrusion when about to finishing 2nd layer

Hi, I have been trying to calibrate my printer for a few days now and I could not resolve the issue shown in the attachment. The printer always over extrude when it is about to finish the second layer. I have recalibrated my z axis, E steps, z probe, 1st layer height and the issue still persist. The first layer is printed on 100% flowrate and intitial layer line width and everything is perfect until the 2nd layer. I have also tried printing with and without retraction.

I am using:
Slicer: Cura
Printer: Self-built with hypercube design
Hot end: E3D chimera
Z-probe: BL-touch
Controller: Duet Wifi

Could anyone help me out please, I am out of ideas ???*???*.
