Print bed crashed into printhead after first time auto home

The first auto home went horribly… i followed the manual perfectly but it fucked up… any help? i can see there is some sort of plastic that is supposed to go through the sensor but the bed would have already crashed into the head before it would detect it?

i had the same problem and my mistake was just cause the arms of the building platform was mounted in the wrong orientation
so, after having put them in the corect sens the problem was resolved ^^
so, check if your arms are in the good sens compared to the manual ^^
i hope this is the problem and you can resolve it , i can also link you to my old post where users propose me different solutions for the same problem before i solved it :
