  After pressing F5, the external terminal doesn't appear as expected, so I cannot start debugging normally.

If you set the "Beta: Use Unicode UTF-8 for worldwide language support" option ON?
At first, I had the same problem with you in my new laptop.

1: (521) ->&"\357\273\2771001-gdb-set target-async on\n"
1: (524) ->&"Undefined command: \"\".  Try \"help\".\n"
1: (524) ->^error,msg="Undefined command: \"\".  Try \"help\"."

And I noticed that the output contains some escape character "\357\273\277". So I thought it may relate to my locale config.
I tried to set the UTF-8 option OFF, and it works.
So it seems that currently the vscode cpp debugger can't work well when "Beta: Use Unicode UTF-8 for worldwide language support" is on.
It seems that this workaround works for me...But still looking forward to a bug fix for this...

Thanks a lot. It now works.
