working on a program using STM32F103C8T6 where I encounter a problem reading files from an SD card

Good evening guys , I'm working on a program using an STM32F103C8T6 microcontroller where I encounter a problem reading files from an SD card. Here's the relevant part of my program:

if (!SD.begin(CHIP_SELECT)) {
    affErreur("CARTE SD");
}
initSeqFP();
dataFile = SD.open("ProgFP.txt"); // Programming file
if (dataFile) {
    uint8_t i = 0;
    while (dataFile.available()) {
        FP[i] = dataFile.readStringUntil('\r\n');
        i++;
    }
    dataFile.close();
    litSeqFP();
}
dataFile = SD.open("MaJDate.txt"); // Date update file
if (dataFile) {
    Serial.println("MaJDate.txt file opened");
    uint16_t v[4];
    uint8_t i = 0;
    while (dataFile.available()) {
        v[i] = dataFile.readStringUntil('\r\n').toInt();
        i++;
    }
    dataFile.close();
    // rtc.setDate(v[0], v[1], v[2], v[3]);
    SD.remove("MaJDate.txt");
}

if (!SD.begin(CHIP_SELECT)) {
    affErreur("CARTE SD");
}
initSeqFP();
dataFile = SD.open("ProgFP.txt"); // Programming file
if (dataFile) {
    uint8_t i = 0;
    while (dataFile.available()) {
        FP[i] = dataFile.readStringUntil('\r\n');
        i++;
    }
    dataFile.close();
    litSeqFP();
}
dataFile = SD.open("MaJDate.txt"); // Date update file
if (dataFile) {
    Serial.println("MaJDate.txt file opened");
    uint16_t v[4];
    uint8_t i = 0;
    while (dataFile.available()) {
        v[i] = dataFile.readStringUntil('\r\n').toInt();
        i++;
    }
    dataFile.close();
    // rtc.setDate(v[0], v[1], v[2], v[3]);
    SD.remove("MaJDate.txt");
}
