Failed to launch: could not launch process: stub exited while waiting for connection: exit status 0

Problem

Hello Suzy, thanks for creating this debugging treasure hunt. I tried to follow your presentation GopherCon 2021: Suzy Mueller - Debugging Treasure Hunt, but quickly came across some problems.

I navigated to main.go, hit the Launch Package button, then this error message showed up: Failed to launch: could not launch process: stub exited while waiting for connection: exit status 0

Here is my system information:
go version go1.17.6 darwin/arm64
macOS Big Sur Version 11.0.1 (20B29) MacBook Air (M1, 2020)

I wonder if you have any suggestions?

Try to run dlv debug from the gophercon directory to see if LLDB error shows any hint.
I've seen cases where either vscode or dlv or go are not for M1, or you need extra config to enable developer mode (e.g. go-delve/delve issue 2382)
