It’s a one-card game implemented, and if you run it about 5 times, you’ll fall into infinite loop more than once, please fix the problem

I don’t know even if I keep looking at it, so I’m asking you a question

My limit is up to here, so I fought a lot with Chatgpt, but if I run it many times, I keep falling into infinite loop
