The most likely answer is that you don’t have a connection in breadboard (the pins should be green, not red which indicates no connection.) Here I made part of your circuit with an intentional error (the ground wire to the transistor is not connected, circled in red here.)
In schematic that shows up like this:
Note no rats nest line from ground to the emitter of the transistor. It should look like this:
which now shows the connection to ground. An alternate way to find this is to left click click on a pin on ground. Everything that is connected (which in this case does not include the transistor!) lights up yellow.
Note the end of the wire shows yellow but the row of pins to the emitter of the transistor does not, as it isn’t connected. As well it is usually best to upload the sketch (the .fzz file) that doesn’t work as then we can load it in to Fritzing so see what is wrong.
