My code was running fine before I did not change anything and I ran it again. Now it doesn't return anything not even an error. It is just stuck on "In [*]".

See problem visually here

This means that Jupyter is still running the kernel. It is possible that you are running an infinite loop within the kernel and that is why it can't complete the execution.

Try manually stopping the kernel by pressing the stop button at the top. If that doesn't work, interrupt it and restart it by going to the "Kernel" menu. This should disconnect it.

Otherwise, I would recommend closing and reopening the notebook. The problem may also be with your code.
