While I know it can only go in 1 of two ways, maybe the problem isn't in how the bobbin is in, maybe it is the route of the thread.
My assumption is you don't seem to pick up the bobbin thread and it bunches. If so the carefully follow the thread to needle you may have by passed the place you put that thread so it maintains tension.
Check that carefully, sometimes that gets overlooked.

Have you checked to be sure the needle is inserted correctly? Try turning it.

sometimes when you break a needle it can cause the machine to
jump time, the machine would have to be taken to a sewing machine
shop to be checked by the technican

try changing needles
clean under the needle plate & in the bobbin area for loose thread or lint
make sure the bobbin is inserted into the bobbin case correctly--if the
machine won't pick the thread up from the bobbin correctly take the bobbin
out of the case & turn it around & try it that way.

check to make sure that the needle was put into the needle holder correctly
all the way up into the needle holder--flat side of the needle to the back side of the machine
if the machine still doesn't up the bobbin thread then
it's possible that when the needle broke that it caused the machine to go out of time which means it has to be retime at a sewing machine shop

it's called being out of time,,and the machine can only be timed by a sewing machine repair technican,, because they have the tools for job

Make sure that the area is clean and free of lint. Change the needle and rethread the machine.

have you tried changing the needle? if it's a new needle is it inserted correctly---flat side to the back of the machine---needle push up in inside the needle holder
have you tried cleaning under the needle plate & in the bobbin area for lint or loose threads?
have you checked the bobbin to make sure it's not warped
have you checked the bobbin is inserted correctly?

if you've already tried these things then the last thing that possible is the machine is out of time & needs to be serviced by a repair shop that have the correct tool to time it
