Can't launch app in debugger in Qt Creator

[ocgltd]

When I start my app normally (non-debug) in Qt Creator it runs fine. But when I run in debug mode the app never seems to start. The following error appears in the system event log:

** UNEXPECTED STATE TRANSITION:  Debugger::Internal::DebuggerEngine(0x6363530, name = "GdbEngine") "State changed from EngineRunRequested(3) to EngineShutdownRequested(14)"

I'm running the latest Qt Creator in Alma Linux 9. Can anyone suggest what is going wrong and needs to be adjusted to allow the app to start in debug mode?

Although I suspect it will work, you should just test gdb /your/executable in a terminal to make sure gdb is fit for purpose.
