Please answer the following before submitting your issue:

1. What version of Delve are you using (dlv version)?

Linux/amd64
Delve Debugger
Version: 1.22.1
Build: $Id: 0c3470054da6feac5f6dcf3e3e5144a64f7a9a48 $

Mac M2
Delve Debugger
Version: 1.21.2
Build: 6d27a40a05f4a9230139a8f9871b475b17af0c02

2. What version of Go are you using? (go version)?
   go version go1.22.1 linux/amd64
   go version go1.21.1 darwin/arm64

3. What operating system and processor architecture are you using?
   targeted container is linux/amd64
   host is mac/m2

4. What did you do?

Basically I'm trying to use devcontainers to debug my application running on an linux/amd64 but hosted via vscode on a Mac M2. Please note I have no issues when the container is a linux/arm64. It works just fine in this setup. However, when its amd64 I see the issue is the debugger failing to get information from the dap running on the container. Here is the output.

Unable to retrieve goroutines: input/output error

Now the program will compile and run fine. Its just I'm unable debug.

5. What did you expect to see?

I expected the ability to debug the application in the container and set breakpoints.

6. What did you see instead?

Failure to attach and debug. Instead targeted program runs.

Not sure if this is expected or an error somewhere.

It is not possible to debug emulated programs.
