It can also lift OK but then travel in a straight line to 0,0. If there is a high clamp it may crash into it. Once you crash a couple of times and figure out the best strategy for you it's no big deal unless your brain is not switched on at the time. Which does occur occasionally
I'm sure F360 will have little foibles as well.

That might be your answer.
Home switches make life much much easier.
But you can potter on without them. You should always home with you Z near the top of travel. Then have soft limits set so it won't go higher than this.
You should be homing Z (setting machine coordinates / G53) and then touching off Z (setting work coordinates/ G54)
Go-to zero script (pesudocode)
G53 G0 Z0 (go to z zero in machine coordinates, which is full up)
G54 G0 X0Y0 (go to xy zero in work coordinates)
