Pause not working on my music shuffle function

Question

My function shuffles an array to make music, but the pause button I started working on didnt work.

When I wanted to add a pause button, and thought keyboard interruptions might work, but it has a ton of errors when i pause with CTRL+C, and I dont even know if using the ENTER key will work to unpause it. Could someone tell me why im getting these errors and how to fix it? thanks in advance
