Cannot reset the tripped circuit breaker

When I turned off one bathroom light last night (Wednesday), the circuit breaker is tripped. Then I cannot reset the tripped circuit breaker - as soon as I reset it it is tripped again.
I did install one light in a bedroom last Saturday. The light works well and was not on when this happened.
I know there must be somewhere with short circuit, but where should I start? The breaker controls nearlly 20 places.
BTW, I did touch the bathroom light weeks ago, trying to get one bulb off. I tried so hard that the "head" where the bulb goes in was damaged and the buld can still not be removed.

Move the wire on the problem breaker to another breaker in the panel the same size and see if the breaker you swapped the wire to trips.

Where are you located? Profile is incomplete. Is the breaker an AFCI?

In Toronto, Canada. How can I check whether it is AFCI?

A typical AFCI breaker. Notice the test button.

Mine does not have the test button, it said 15 instead of 20. I took several pictures but not clear as it is too dark in the basement. Only one is better. It may help.

Can you take a picture of the handle? Turn on flash if possible.

Just to verify you are resetting the breaker by turning it all the way off then on aren't you? Disconnect the wire from it and see if you can reset it.

I pushed it downwards a bit then pushed it upwards. Teh breaker could stay 1 or 2 seconds, then tripped again. How can disconnect the wire from the breaker?

Turn the breaker off, turn the main breaker off, loosen the screw holding the wire and pull the wire out.

CAUTION! Areas around the main breaker remain energized even when the main breaker is off.

When the fixture was twisted a wire may have gotten nicked and is shorting to ground. Remove the problem fixture and see if the breaker resets.

Thank you for all the information. Problem solved. It seems the switch for the bathroom light has connection issue. I will change it soon.
