No response

Additional Information

No response

Start with the supplied debugger configuration and launch log, especially the target extended-remote command, miDebuggerServerAddress, miDebuggerPath, and program path. Reproduce the remote attach failure and trace how the C/C++ extension handles these paths; done means identifying the source of the “No such file or directory” error and confirming a fix with a regression test.
