this condition is not correct

while (fast->next != NULL && fast != NULL) {
		fast = fast->next->next; // fast moves 2 steps
		slow = slow->next; // slow moves 1 step
	}

first you have to check fast then fast->next
if fast is null then you are checking fast->next which is actually giving run error
correct one

while (fast != NULL && fast->next != NULL) {
		fast = fast->next->next; // fast moves 2 steps
		slow = slow->next; // slow moves 1 step
	}
