I'm working on an ESP8266-based water level monitoring system using an ultrasonic sensor and an I2C LCD. The problem I'm facing is that sometimes the ESP8266 does not boot properly when powered on for the first time. However, if I turn the power off and on again, it boots and works fine.

Microcontroller: ESP8266 (NodeMCU)
Peripherals:Peripherals:
Ultrasonic sensor (JSN-SR04T)
16x2 I2C LCD
Buzzer
Push button
Wiring:Wiring:
const int trigPin = D3; const int trigPin2 = D8; const int echoPin = D0; const int echoPin2 = D6; const int overflow = D4; const int buzzer_out1 = D5; const int push_Button = D7;

const int overflow = D4;
const int buzzer_out1 = D5;
const int push_Button = D7;
LCD Connections:LCD Connections:
SCL: D1
SDA: D2
Issue Description:Issue Description:
When I first power on the ESP8266, it sometimes does not boot properly. The LCD either remains blank or shows a pattern of blocks (see attached image). If I turn off the power and turn it back on immediately, the ESP8266 boots and works correctly. The issue is inconsistent but happens frequently enough to be a concern.
Any insights on what might be causing this and how to fix it would be greatly appreciated!
