Single sensor not reading with V3.3.2 Arduino and any version > 3.9.0

I don´t know if this is related to the ESP32 version or the temperature library but..

Any version later than V3.9.0 of DallasTemperature returns -128 when reading the DS18B20

My code was working fine until I updated the library. I have tried several versions but any higher than 3.9.0 have the same result.
Reverting to the 3.9.0 version and everything works again.

I´m running V3.3.2 of the Arduino ESP32 code. I haven´t tried on any earlier versions.
Other than changing the version of the library nothing else on my project changed between a working and non-working version.

My code is very simple for the test, in setup:
`
#define ONE_WIRE_BUS 14
OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);

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

float temperature;

sensors.requestTemperatures();
vTaskDelay(1500);

temperature = sensors.getTempCByIndex(0);
Serial.printf("Startup Celsius temperature:%0.2f\n", temperature);

etc..

Prior to V4 it seems sensors.begin() was not required, now it is..

I've never known it not to work without sensors.begin(), it must have worked by coincidence. Glad you got it sorted!
