esp32 panic'ed

[aymancom]

"Hello all, I have an ESP32 with an SD card module. I want to read data from the SD card and save it in variables. However, after the ESP reads the data, it panics.

this is the code:
`
#include <SPI.h>
#include <SD.h>
#include "FS.h"
String DataTemp;
String Parametro;
short i;
String AllData[7];
int Pointer = 0;
int count = 0;

void readFile(fs::FS &fs, const char * path){
Serial.printf("Reading file: %s\n", path);

File file = fs.open(path);
if(!file){
    Serial.println("Failed to open file for reading");
    return;
}

Serial.print("Read from file: ");
while(file.available()){
    char c = file.read(); 
     if (isPrintable(c)) { // 
     DataTemp.concat(c); 
    
   } 
   else if (c == '\n') { // End of line
    
  Parametro = DataTemp;  // 

  DataTemp = "";  // Reset to null ready to read the next line
  Serial.print("The parameter is: ");
  Serial.println(Parametro); // Show us the valu
  AllData[Pointer] = Parametro;
    Pointer++;

}
}

for (count=0;count<5;count++) {
     
     Serial.println(AllData[count]);
     delay(100);
   } 

   delay(100);
file.close();

}

void setup() {

Serial.begin(115200);
delay(10);

if(!SD.begin(5)){
    Serial.println("Card Mount Failed");
    return;
}
uint8_t cardType = SD.cardType();

if(cardType == CARD_NONE){
    Serial.println("No SD card attached");
    return;
}

Serial.print("SD Card Type: ");
if(cardType == CARD_MMC){
    Serial.println("MMC");
} else if(cardType == CARD_SD){
    Serial.println("SDSC");
}else if(cardType == CARD_SDHC){
    Serial.println("SDHC");
} else {
    Serial.println("UNKNOWN");
}

}

void loop() {
readFile(SD,"/data.txt");
delay(20000);

}

`

Can anyone help me with this problem?, and how I can save data from one line in this form (0,69.50,20.10) in variables x=0 y=69.50 z=20.10 ?
