This is the problem.

because yoru bed is way way way higher than the printer thinks it is. Printer only know the position of the nozzle from the position of Z endstop or probe like bltouch. Z offset just offset the print, not the homing so any change in Z offset does not have any effect.

# midnight tulip How do I lower the bed?

With ABL you don't need to physically move the bed (but it is recommanded to tram it to some degree to minimize corrections). Just google how to tell to your printer what is real Z distance from the probe trigger point to nozzle. Currently printer thinks the distance is big and move the Z too far down.

#

Usually the distance from nozzle to probe is few mm but in your case it looks like even cm or more.

@midnight tulip Z offset do something else.... How to explain it, home will find your zero and Z offset will move the Z during the print in case you have a problem with adhesion for example.
