重新启动后，线程无法在 while 循环中再次运行

我这里有一个C++代码，它将制作一个游戏，它将根据键盘输入生成随机数，如果数字是偶数，分数会增加。如果分数是10，你赢了，你可以重新开始或退出游戏。

using namespace std;
int score = 0, run = 1;
char inp = 'z';
void the_game() {
int x = 0;
while (run) {
if ('a' <= inp && inp <= 'j') {  
srand((unsigned)time(NULL));
x = (rand() % 11) * 2;  //if 'a' <= inp <= 'j', x is always even
cout << "Number: " << x << endl;
}
else {                      // and if not, x is random
srand((unsigned)time(NULL));
x = (rand() % 11);
cout << "Number: " << x << endl;
}
if (x % 2 == 0) {
score++;
cout << "Current Score: " << score << "n";
}
if (score == 10) {
run = 0; 
cout << "You Win! press R to restart and others to exit" ;
}
Sleep(1000);
}
}
void ExitGame(HANDLE t) {
system("cls");
TerminateThread(t, 0);
}

总的来说，我使用线程来运行游戏，同时从键盘输入，如下所示

int main() {
thread t1(the_game);
HANDLE handle_t1 = t1.native_handle();
cout << "The we_are_even gamen";
while (true) {
inp = _getch();
if (run == 1) 
ResumeThread(handle_t1);
else{   //run == 0
if (inp == 'r') {
system("cls");
cout << "The we_are_even gamen";
run = 1; //restart game
}
else {  //if inp != 'r', exit the game
ExitGame(handle_t1);
t1.join();
return 0;
}
}
}
}

问题是，在我赢得游戏并按"r"重新启动后，线程不会再次运行 虽然应该恢复。我在这里哪里犯了错误？我该如何解决它？我试图在 run = 0 时暂停它并再次恢复，但无济于事。
