I am using the following configuration to start a debug session and immediately stop it via the "Stop Debugger" action in Qt Creator:

• Host OS Windows
• Qt Creator 8.0
• Android x86_64 (Emulator)
• NDK 23.1 (LLDB 12.0.8)

The application starts properly, the debugger is doing well (breaking on a breakpoint would work, but I won't in this test).
When I press "Stop Debugger", the UI goes into an invalid state:

If I do the above in Qt Creator 7.0 with the same combination of target, NDK, etc., stopping works well.

The start up in Qt Creator 7.0 and 8.0 create essentially the same log: DebuggerLog_Start.txt
But the logs after the stopping look different:

• Qt Creator 7.0: DebuggerLog_Stop_QtC_7.0.txt
• Qt Creator 8.0: DebuggerLog_Stop_QtC_8.0.txt

The stopping diverges after 7.0 registers a "dLLDB PROCESS ERROR: 1" which 8.0 does not show in its log.
