'Why is Xcode showing me SIGSTOP signal at cin?

I tested the code on Dev c++, and it's totally fine. But when I try to run it on Xcode, it kept showing me "Thread 1: signal SIGSTOP"

Here is the main function of my code.

int main(){
    ios::sync_with_stdio(false);
    cin.tie(NULL);
    cin>>n; //where the warning is shown
    for(int i=0;i<n;i++){
        cin>>length;
        cin>>pw;
        cout<<"Case #"<<i+1<<": ";
        solve();
    }
    return 0;
    }

Also, this is shown in the console:

2022-05-23 12:07:56.463843+0800 test.cpp[67390:5076465] [default] error finding potential wrapper bundle for node <FSNode 0x10117f580> { isDir = ?, path = '/Users/rb33l1/Library/Developer/Xcode/DerivedData/test.cpp-hglkwauzjfshikatnvjoriekjqzk/Build/Products/Debug' }: Error Domain=NSOSStatusErrorDomain Code=-10811 "kLSNotAnApplicationErr: Item needs to be an application, but is not" UserInfo={_LSLine=1579, _LSFunction=wrapperBundleNodeForWrappedNode}

Does anyone have similar experience dealing with this problem? What should I do next? Any help will be much appreciated
