为什么重新加载2次后内容脚本无法继续执行？

Question

我一直在扩展，以确保始终能在www.frikitrivial.com上获胜。所有机制都在内容脚本文件中，每次选项卡的url等于“ struct padding”时，都必须重新加载页面，但是经过2次后，它停止了，我的意思是内容脚本不再执行。我已经检查了在脚本开始处编写console.log（）的方法。

谢谢。

这是内容脚本文件中的代码（您可以忽略其中的大部分内容）。

console.log( "Iniciando partida..." )


let question, answers, _answers

if( location.href !==  "http://www.frikitrivial.com/end.php" ){
    question = document.querySelectorAll("div.question")[0].textContent
    answers = []
    _answers = document.querySelectorAll("a.answer")
    
    document.querySelectorAll("a.answer").forEach( e => answers.push( e.textContent ) )
}


function click( s ) {
    let c
    for( let i = 0; i < 4; i++ ) {
        if( s === _answers[i].textContent ) {
            c = _answers[i]
        }
    }
    console.log( "El siguiente elemento va a ser clickado..." )
    console.log( c )
    c.click()
}

chrome.storage.sync.get(["lastClicked"], function(result){
    if( result.lastClicked ) {
        console.log( "Leido lastClicked..." )
        if( location.href === "http://www.frikitrivial.com/end.php" ) { // manejamos fallo
            console.log( "Manejando fallo de pregunta..." )
            chrome.storage.sync.set({
                [result.lastClicked.question]: {
                    question: result.lastClicked.question,
                    answers: result.lastClicked.answers.shift(),
                    answered: false
                }
            }, () => chrome.runtime.sendMessage({redirect: "https://www.frikitrivial.com/game.php"}))
        } else { // actualizamos el estado de la ultima pregunta respondida
            if( !result.lastClicked.answered ){
                console.log( "Manejando lastClicked not answered..." )
                chrome.storage.sync.set({
                    [result.lastClicked.question]: {

                }, answerNewQuestion)
            } else {
                console.log( "Manejando lastClicked answered..." )
                answerNewQuestion()
            }
        }
    } else {
        answerNewQuestion()
    }
})

function answerNewQuestion() {
    chrome.storage.sync.get([question], function(result){
        if( result.question ) { // si ya hemos intentado responder esta pregunta alguna vez
            if( result.question.answered ) {

                        answered: result.question.answered
                    }
                }, () => click( result.question.answers[0] ) )
            } else {
                chrome.storage.sync.set( {
                    lastClicked: {
                        question: result.question.question,
                        answers: result.question.answers,
                        answered: result.question.answered
                    }
                }, () => click( result.question.answers[0] ) )
            }
        } else {
            chrome.storage.sync.set( {
                [question]: {
                    question: question,
                    answers: answers,
                    answered: false

            }, function( result ){
                chrome.storage.sync.set( {
                    lastClicked: {
                        question: question,

            })
        }
    })  
}

这是manifest.json！
