[Not constantly reproducible] Qt Creator 12 fails to launch debugger on macOS14

It is NOT always reproducible. Although the original reporter reported such issue, we have tested on multiple macOS14 devices but failed to reproduce the issue. Just in case, I filed this bug report after an internal discussion.

According to original reporter, after placing a breakpoint and starting application in debug mode (F5), the following log gets printed in loop and debugger cannot be started:

QML Debugger: Socket state changed to QAbstractSocket::HostLookupState
sQML Debugger: Socket state changed to QAbstractSocket::ConnectingState
sQML Debugger: Socket state changed to QAbstractSocket::UnconnectedState
wQML Debugger: Error: QAbstractSocket::ConnectionRefusedError

If it's true, then it sounds like "cannot connect to debugger server" issue.

One thing is that such log also happens to me - but only once. After the initial failure, debugger starts normally when trying to connect for the 2nd time.

Update: original report provided a debugger log.
