Having trouble after installing BLTouch and new firmware

Hi everybody, greetings from Holland.

Last month I bought the Ender 3 V2 from Creality. I find manually leveling the bed irritating so iI decided the install the Creality BL Touch.
I carefully watched the Dr Vax video’s severall times ans followed up the instructions.
The bed was four/five times manually leveled before the first print. The G-code of Creality Slicer 4.2 was adjusted with the code I found on this forum.

It looks like everything works as expected; but…
The prints are damaged and not like the ones I printed before installing the BL Touch.
I have printed this image several times with the same PLA and the same temperatures (200/60) before installing the BLTouch and they came out wonderfull.

In the picture you can see the print the way it comes out after installing BL Touch. At the front it looks OK but at the rear it is messy.
At the bottom of this topic is the G-code I used.

Can anyone help me to solve this problem ?

Not sure where you got that startup code but all you have to do is put a G29 after the G28 and you should be good to go.

; Ender 3 Custom Start G-code
G92 E0 ; Reset Extruder
G28 ; Home all axes
G29 ; Auto Bed Leveling

Thats what the first 4 lines of mine looks like.

hmmmm, there is a G29, after the G28 and G28 Z.
