Hello
I have an Ender 3 Pro and i recently managed to ram my hotend into the printbed while trying to calibrate my bltouch z offset.
since then in the lower left corner nothing wants to stick to the bed anymore.
I have also switched around the buildplate but its still the same problem

You are still printing too high, so further adjustment of Z offset is needed. Graphic for reference:

If you still have curling in the corner, after perfecting first layer, then collision might have done some damage - could be either BLTouch or mechanics of the printer (axis alignment, X/Y carriage, bed surface, etc)
Then i would have few additional questions:
Can you do probe repeatability test?
Do you have enabled ABL? Did specified compensation (settings or gcode)?
Is extruder carriage (x axis) perpendicular to bed (y axis)?
