qtcreator can't quit debug program on Mac OS X 13

On mac os X 13 high sierra,

while debugging a program, if I click the stop button of the debugger ui to stop the program, the program will not quit, instead, it will stuck at the following call stack:

1 poll 0x7fff6add74ea
2 qt_safe_poll(pollfd *, unsigned int, timespec const *) 0x10059e380
3 QEventDispatcherUNIX::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) 0x10059f845
4 QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>) 0x100545631
5 QCoreApplication::exec() 0x10054a099
6 main main.cpp 21 0x100003acc
7 start 0x7fff6ac86145

clicking the stop button for multiple times won't work either.

the only way to resolve this is restart qtcreator. I will see a dialog saying "lldb session terminated"
