Why am I getting Unhandled exception thrown: read access violation

I do not understand what is happening.

I made a program to get a char input and output it back. I receive this exception every time I press enter to input a value into the program:

Unhandled exception thrown: read access violation. this->_format_it was 0x38.

I have tried a large arrangement of inputs and it seems that no matter what I input it will throw this at me. In fact, This is almost exactly the code my college gave me

Here is the code:

// Card Value
// cardValue.c
#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
int main(void)
{
    char rank = 'c';

    printf("Enter the card rank : ");
    scanf("%c", &rank);
    printf(rank);

    return 0;
}

Removing the address operator will result in another exception:

Unhandled exception at 0x79B498F1 (ucrtbased.dll) in Card Decks.exe: 0xC0000005: Access violation writing location 0x00000063.

printf()'s first argument must be a pointer to a format string, not a char. You could do

printf("%c", rank);
