System Hangs by writing delay after Timer_init() - c

Question

I am facing a strange issue while programming PIC18f45k22. I am initiating system modules and then I write a blocking delay for 3 seconds to wait for a touch screen to start (because I need to send some information to this screen). But when I do this I discovered that when I initiate timer before writing the delay, I discover that the system freezes.
This is the code that I used
NOTE: all the functions work fine without any problem.
void main(void) {
Sys_Init();
__delay_ms(3000);
while(1){
//Code
}
System initiation code
void Sys_Init(void) {
Delay_XTAL();
OSCILLATOR_Init();
DIGITAL_PIN_STATE();
ANALOG_PIN_STATE();
ADC_INIT(); //change clock select pins when oscillator changes
Spi_Init();
DHT22_init();
Uart_Init(9600); //initiate UART (change baud values when oscillator value changed)
Timer1_Init(); //initiate timer one (change prescaler and counter value if oscillator value changes)
}
Timer code
void Timer1_Init(void){ //for interrupt program use this function
//Prescaler 1:1; TMR1 Preload = 61536; Actual Interrupt Time : 1 ms
T1CON = 0x01;
TMR1IF = 0;
TMR1H = 0xF0;
TMR1L = 0x60;
TMR1IE = 1;
INTCON = 0xC0;
}
Interrupt code
void __interrupt() ISR (void){
Timer1();
}
void Timer1(void){ //for interrupt program
if (TMR1IF){
cnt1++;
TMR1H = 0xF0; //overflow every 1 ms
TMR1L = 0x60;
TMR1IF = 0;
}
}
