How to halt Julia mid execution?

I’m running Julia in Jupyter Notebook. My program was recording a large amount of data that I wanted to keep in a large array final_ans. It was about 60% done and I just wanted to give up and save what I had so far. I was actually able to do this yesterday when the program ran out of memory and stopped midway by itself. So how do I just halt the running of the code? Kernel>Interrupt didn’t do anything. Should I raise an issue over that? Kernel>restart works but all data is lost.
