Unable to start debugging. Unexpected LLDB output from command "-exec-run"

[takayuki74]

Hello!

When I try to debug, the debug console reports an error:

ERROR: Unable to start debugging. Unexpected LLDB output from command "-exec-run". process exited with status -1 (attach failed ((os/kern) invalid argument))

I could successfully start debugging through lldb command.
Could you kindly help me get out of this?
