OLED display on I2C causes esp8266 to reset

Question

I have connected two temp sensors and an OLED display to a NodeMCU using I2C. When the program reaches the instruction to print the measurements on the display the program crashes and NodeMCU resets itself. In the serial monitor I see "rst cause 2". I did search about this online but couldn't find a similar issue involving an OLED. I wonder what is causing this reset and how to fix it?

#include <Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BME280.h>
#include <Sodaq_SHT2x.h>
#include <Adafruit_SSD1306.h>

//defining OLED dimensions
#define WIDTH 128
#define HEIGHT 32
#define OLED_RESET -1

Adafruit_SSD1306 display(OLED_RESET);


Adafruit_BME280 bme1; // I2C

void setup() {
  Serial.begin(115200);

  Wire.begin();
  display.begin(SSD1306_SWITCHCAPVCC, 0x3C); // initiate OLED

  Serial.println(F("BME280 test"));

  //BME280 sensor 1
  if (! bme1.begin(0x77, &Wire)) {
    Serial.println("Could not find a valid BME280 sensor, check wiring!");
    while (1);
  }

  //  weather monitoring
//  Serial.println("-- Weather Station Scenario --");
//  Serial.println("forced mode, 1x temperature / 1x humidity / 1x pressure oversampling,");
//  Serial.println("filter off");
  bme1.setSampling(Adafruit_BME280::MODE_FORCED,
                   Adafruit_BME280::SAMPLING_X1, // temperature
                   Adafruit_BME280::SAMPLING_X1, // pressure
