Why is it not taking the User's input

enter image description here System.out.println("Welcome to Rock, Paper Scissors!");

        // User enters the number of rounds they want to play
        // Rounds range from 1(min) to 10 (max)
        System.out.println("Let's begin with the number of rounds you would like to play: " );
        stringRounds = sc.nextLine();  
        
        int rounds = Integer.parseInt(stringRounds);
            
        while (rounds < 1 || rounds > 10) {
            System.out.println(stringRounds + (" is out of my range. Please try again."));
            stringRounds = sc.nextLine();
            rounds = Integer.parseInt(stringRounds);
        }
        System.out.println(stringRounds + (" sounds good to me. Let's Get Started!"));

        int compChoice = rnd.nextInt();
        
        switch (compChoice) {
            case 1:
                randomChoice = "Rock";
                break;
            case 2:
                randomChoice = "Paper";
                break;
            case 3:
                randomChoice = "Scissors";
                break;
            default:
                break;
        }
        
         // User will choose Rock, Paper, or Scissors
        System.out.println("Pick your move: Rock, Paper, Scissors?");    
        int userChoice = sc.nextInt();
        //t userChoice = Integer.parseInt(stringUser);
        
        if (userChoice == compChoice) {
            System.out.println("IT'S A TIE!!");
        }
        else if ("Rock".equals(userChoice))
            if ("Scissors".equals(compChoice))
                System.out.println (("Rock breaks Scissors!") + userChoice + (" wins this round!"));
            else if ("Paper".equals(compChoice))
                System.out.println(("Paper wraps Rock!") + compChoice + (" wins this round!"));
        else if ("Paper".equals(userChoice))
            if ("Rock".equals(compChoice))
                System.out.println(("Paper wraps Rock!") + userChoice + (" wins this round!"));
            else if ("Scissors".equals(compChoice))
                System.out.println(("Scissors cuts Paper") + compChoice + (" wins this round!"));
        else if ("Scissors".equals(userChoice))

                System.out.println(("Scissors cuts Paper") + userChoice + (" wins this round!"));
            else if ("Rock".equals(compChoice))
                System.out.println(("Rock breaks Scissors!") + compChoice + (" wins this round!"));
        
        else
                System.out.println("Invalid user input!");
    
    }

"Exception in thread "main" java.util.InputMismatchException"

It lets me enter number of rounds, but it doesn't execute when I enter User's choice. I tried debugging and it's not really showing me what the error is. Unless I'm debugging wrong(most likely).
