Additional Information

More background info on this. My application disables ptrace hardening at runtime using a call to prctl, making me able to attach with regular CLI GDB from the command line, however, I want to use VS Code. I have already opened an issue in the MIDebugEngine, where the message comes from: microsoft/MIEngine#1388.

Opening a bug issue here as well, as I was unable to input the password when prompted in the VS Code terminal. If this issue is external, please point me in the right direction. Thanks!

We will have to investigate what will need to be done for this.
