I’ve been trying to print an ornament for the past week. I’ve calibrated the print bed multiple times and even used a level on it to see if there were any issues.
Hitting print
I had the same issue. Next to the nozzle is a smal square probe(magnetic) with Sealed screws. This one caused the collision
Lose the screws a little and raise the probe until its not lower than the nozzle

Retraction was enabled but z hop was not. I enabled (and also happened to switch to a different PLA) and the print worked fine. I switched back to the original PLA just to try it and see if it works.
