I tried using 3 different arduinos nanos, changed the usb cable, reinstalled the arduino ide, checked port and nothing.

Yesterday i was trying to work with a VL53L0X and after an hour the error started to come

Please help!!!

Did you picked the right board? I remembered having the same errors once. It was due to i was uploading to Due while I configured it as Uno.
