Why is this crashing?

Hello all-

I had, I thought, successfully completed the project "Build a random quote generator."
However my finished project randomly crashes when generating new quotes.
Would anyone be able to shine some light on why this is?

Randomly? It always crashes when the button is clicked the second time. It’s quite predictable.

Good job in fixing it.

Thanks- late night of coding… almost missed the char length limit on twitter!
