Bathroom light switch not turning on light, indicator LED still glowing—what could be wrong?

Hello, my problem arose today exactly 15 minutes ago.
Going to the bathroom, I wanted to turn on the light, but when I pressed the switch, nothing happened.
I checked if the plugs popped out and if I could turn on the light in other rooms - with positive results.

When he wants to switch the switch, he does it extraordinary (we stay by the bathroom), as if reluctantly. The light does not turn on, and there is still a glowing light next to the switch that signals that the light is turned off.
I'm not an adult myself, and an adult will appear in a few hours.

Does anyone know where I was at fault, what could have happened and how to fix it?

not ticking, the responsible person will turn off the protections and check if the switch mechanism is not working - such faults happen
PS: the mentioned "plugs" were on or off after trying to turn on the light?

Unfortunately, the switch needs to be replaced, as with everything, the switch breaks down after some time of use. It has burned out contacts or mechanical damage (this is more likely because you write that it is resistant). Adult only replacement.

The fact that I should not do anything, I am aware, I just wanted to know what happened and what to do to get the light back.

The traffic jams were on all the time.
When Dad comes back, I will involve him in replacing the switch
I just hope it all comes out without a short circuit :)

Gentlemen who replied in much faster time than I expected (the answer was I think complete, short and concise) as a thank you "I will give" by point. Greetings.
