2 I2C and 1 UART are not working simultaneously in ESP32

I have a project in which I have to monitor Acceleration of the subject, Location and Pulse + SpO2 of the subject. So, I've written this program to check data from MAX30100 Pulse Oxi sensor and MPU6050 Accelero and Gyroscope sensor using ESP32 -

This program works completely fine. No issues at all.

#include <Wire.h>
    #include "MAX30100_PulseOximeter.h"
    #define REPORTING_PERIOD_MS 1000
    #define BLYNK_PRINT Serial
    #include <Blynk.h>
    #include <WiFi.h>
    #include <BlynkSimpleEsp32.h>
    
    char auth[] = "*********************";   
    
    // For Pulse sensor
    PulseOximeter pox;
    float BPM, SpO2;
    uint32_t tsLastReport = 0;
    
    // For Accelerometer sensor
    const int MPU_addr=0x68;
    int16_t accelX, accelY, accelZ, gyroX, gyroY, gyroZ;
    float gForceX, gForceY, gForceZ,rotX, rotY, rotZ;
    
    void onBeatDetected()
    {
        Serial.println("Beat Detected!");
    }
    
    void setup() {
      Serial.begin(115200);

      WiFi.begin("TP-Link", "**********");
    
      // Wait for wifi to be connected
      uint32_t notConnectedCounter = 0;
      while (WiFi.status() != WL_CONNECTED) {
          delay(100);
          Serial.println("Wifi connecting...");
          notConnectedCounter++;
          if(notConnectedCounter > 50) { // Reset board if not connected after 5s
              Serial.println("Resetting due to Wifi not connecting...");
              ESP.restart();
          }
      }
      Serial.print("Wifi connected, IP address: ");
      Serial.println(WiFi.localIP());
      
      Blynk.begin(auth,"TP-Link_380B", "installation*500");
      Serial.println("Initializing Pulse Oximeter..");
     
        if (!pox.begin())
        {
             Serial.println("FAILED");
             for(;;);
        }
        else
        {
             Serial.println("SUCCESS");
             pox.setOnBeatDetectedCallback(onBeatDetected);
        }
     
        // The default current for the IR LED is 50mA and it could be changed by uncommenting the following line.
            pox.setIRLedCurrent(MAX30100_LED_CURR_7_6MA);
            
      Wire1.begin(32,33,100000); 
      Wire1.beginTransmission(MPU_addr);
      Wire1.write(0x6B);  // PWR_MGMT_1 register

      accelX=Wire1.read()<<8|Wire1.read();  // 0x3B (ACCEL_XOUT_H) & 0x3C (ACCEL_XOUT_L)
      accelY=Wire1.read()<<8|Wire1.read();  // 0x3D (ACCEL_YOUT_H) & 0x3E (ACCEL_YOUT_L)

      gForceX = (accelX-2050) / 16384.0;
      gForceY = (accelY-77) / 16384.0; 
      gForceZ = (accelZ-1947) / 16384.0;
    
      rotX = (gyroX+270) / 131.0;
      rotY = (gyroY-351) / 131.0; 
      rotZ = (gyroZ+136) / 131.0;
    
      // calculating Amplitute vactor for 3 axis
      float Raw_Amp = pow(pow(gForceX,2)+pow(gForceY,2)+pow(gForceZ,2),0.5);
      int Amp = Raw_Amp * 10;  // Mulitiplied by 10 bcz values are between 0 to 1
      int angleChange = pow(pow(rotX,2)+pow(rotY,2)+pow(rotZ,2),0.5);
    
      // Reading data from pulseoximeter sensor
      pox.update();
      BPM = pox.getHeartRate();
      SpO2 = pox.getSpO2();
    
      // Uploading data to Blynk server AND printing data on serial monitor
      if (millis() - tsLastReport > REPORTING_PERIOD_MS)
        {
          Blynk.run();
          
          Blynk.virtualWrite(V3, BPM);
          Blynk.virtualWrite(V4, SpO2);
          
    
          Serial.println(Amp);
          Serial.println(angleChange);
    
          Serial.print("Heart rate:");
          Serial.print(BPM);
          Serial.print(" bpm / SpO2:");
          Serial.print(SpO2);
          Serial.println(" %");
    
          tsLastReport = millis();
        }
    }

Now I added GPS, so that I can track the location too. And GPS is working along with accelerometer but Pulse oximeter sensor is not working - Output from that is 0 and the rest of the sensors are producing the expected outputs. Program for that is given below

Will you please help me with this. What's wrong with the program.
