How to prevent ADC interrupt from affecting LCD display on AVR MCU?

I am working with an AVR MCU and have encountered an issue with an interrupt routine affecting my LCD display. Specifically, I have an analog potentiometer connected to an analog pin, and the interrupt associated with the ADC conversion seems to be interfering with the LCD_display method. I need to ensure that interrupts are paused while executing the LCD update code to avoid conflicts.

I used `cli()` to disable interrupts before updating the LCD and `sei()` to re-enable interrupts after the update is complete. This prevents the ADC interrupt from interfering with the LCD display operations.

Is there a better way to manage interrupt handling without affecting the LCD display? my code snippet is in the attached file.
