Bug Report for https://neetcode.io/problems/contains-duplicate-ii

When I try to Run/Submit solution (as below) in C++ issue occurs. For simple Run, only bottom Console Output comes out but it is totally empty (screenshot 1).
For Submit, I receive 'Unknown' response in Submissions tab (screenshot 2).

On leetcode website, the same exact code works and passes all the tests. I am attaching code and leetcode pass prove (screenshot 3)

Code:

 class Solution {
 public:

    bool containsNearbyDuplicate(vector<int>& nums, int k) {

        int L = 0;
        unordered_set<int> window;

        for (int R = 0; R < nums.size(); R++) {

            if (window.count(nums[R])) {
                return true;
            }

            window.insert(nums[R]);

            if (window.size() > k) {
                window.erase(nums[L]);
                L++;
            }
        }
        return false;
    }
 };
