Program execution stops at u8g2.begin(); when using MegaCoreX

[RMCybernetics]

Seems an identical issue to #1750
However I am using an ATMega4808 with MegaCoreX. Could the issue be with u8g2 as the previous person had the same issue with a totally different board?

Example code;

#include <Wire.h>
#include <U8g2lib.h>

#define LED 1

U8G2_SH1106_128X64_NONAME_F_HW_I2C u8g2{U8G2_R0, /* reset=*/ U8X8_PIN_NONE};

void setup() {

	pinMode(LED,OUTPUT);

  Wire.begin(0x7A);             // <----  Without this line, execution stops at u8g2.begin()
  u8g2.setI2CAddress(0x7A);			// 0x3D
	Wire.pins(10,11);
  
	u8g2.begin();
	u8g2.clearBuffer();					      // clear the diplay
	u8g2.setFont(u8g2_font_5x8_mf);		// 5x8 pixel font

  // Put something on the screen
  u8g2.drawStr(10, 10, "TEST");     // Nothing is on the screen :(
  u8g2.sendBuffer();
}

void loop() {

    digitalWrite(LED,HIGH); // Turn on an LED to show program is running

}

Not sure what I can do here. Doesn't seem to be a u8g2 problem.
Maybe you missed pull up resistors?
