Correct crystal pinout, using recommended capacitance values, and everything is wired up correctly as far as I can see.
On paper the crystal should work ... which leaves the obvious candidates of shorts or misplaced components on the PCB.
I don't see JLCPCB part numbers in the BOM, could be a situation where something in the part matching process went wrong and there are now 100nF caps on the actual PCB instead of the 15pF ones. Definitely something to double check.

You'd be surprised how many boards get made with nothing more then KiCad, a soldering iron and a multimeter.I would presume someone producing such a board would have access to suitable tools to figure it out, have access to people experienced with hardware debugging. Hands-on debugging is always easier than remote debugging.
