float variable getting low value with BME280

Using Arduino Sensors
3

I didn’t post my complete code because it’s over 1000 lines and the most of it is unrelevant to my problem.
I removed everything unrelevant to temp measurements from my code and tried this minimized code which appears to have the same issue.

#include <Arduino.h>
#include <SPI.h>
#include <Wire.h>
#include <U8g2lib.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BME280.h>
#include <EEPROM.h>

#define ON 1
#define OFF 0

float temperature = 0;

float target = 22.0;

int error = 0;

int heating = OFF;

unsigned long currentMillis;
unsigned long previousMillis;
unsigned long previousLCDMillis;

Adafruit_BME280 bme;

const int relay = 5;
const int backlightPin = 6;

U8G2_ST7565_64128N_F_4W_SW_SPI u8g2(
	U8G2_MIRROR,
	/* clock=*/ 13,
	/* data=*/ 11,
	/* cs=*/ 10,
	/* dc=*/ 9,
	/* reset=*/ 8);

void setup(void) {

	pinMode(relay, OUTPUT);
	digitalWrite(relay, HIGH);


	pinMode(backlightPin, OUTPUT);
	digitalWrite(backlightPin, HIGH);

	u8g2.begin();
	u8g2.setContrast(170);


	bool status;
	status = bme.begin(0x76);  //The I2C address of the sensor I use is 0x76
	bme.setSampling(Adafruit_BME280::MODE_FORCED,
		Adafruit_BME280::SAMPLING_X1, // temperature
		Adafruit_BME280::SAMPLING_X1, // pressure
		Adafruit_BME280::SAMPLING_X1, // humidity
		Adafruit_BME280::FILTER_OFF,
		Adafruit_BME280::STANDBY_MS_1000);

	currentMillis = millis();
}

void loop() {

	currentMillis = millis();


	if (!error){
		if ( ! heating ){
			if (target > temperature){
				heatingON();
			}
		}
		else{
			if (target < temperature){
				heatingOFF();
			}
		}

		if ((unsigned long)(currentMillis - previousMillis) >= 2000) {
			previousMillis = currentMillis;
			readBME280();
		}

	}
	else heatingOFF();

	if ((unsigned long)(currentMillis - previousLCDMillis) >= 200) {
		previousLCDMillis = currentMillis;
		updateLCD();
	}
}

void heatingON(){
	heating = ON;
	digitalWrite(relay, LOW);
}

void heatingOFF(){
	heating = OFF;
	digitalWrite(relay, HIGH);
}


void readBME280(){
	bme.takeForcedMeasurement();
	temperature = bme.readTemperature();
	if (!((temperature >= 0) && (temperature <= 35))) error = 1;
}

void updateLCD(){

	u8g2.clearBuffer();	
	u8g2.setFont(u8g2_font_freedoomr25_tn);
	u8g2.setFontMode(1);
	u8g2.setDrawColor(1);
	if (!error){
		u8g2.setCursor(2,29);
		u8g2.print(temperature,1);
		u8g2.setCursor(2,63);
		u8g2.print(target,1);
	}
	else{
		u8g2.setCursor(2,29);
		u8g2.print(temperature,1);
		u8g2.drawStr(2,63,"ERROR!");
	}

	u8g2.sendBuffer();
}

I’m pretty sure that -214748368.0 is a minned out value but I don’t know how the Adafruit_BME280 library reads data from my sensor and why it returns that minned out value.
I’d like to know if it could be a hardware related issue. Could this mean that it doesn’t find a connected sensor?
