Command failed: EOF when hitting a breakpoint

[gitkrtuck]

What version of Delve are you using (dlv version)? v1.9.1, v1.20.1, (and v1.8.0 w/go1.18.10)
What version of Go are you using? (go version)? go1.19.6, go1.21.0, go1.21.1, go1.19.10
What operating system and processor architecture are you using? macOS 14.1 (23B74) Sonoma. (can't go back to Ventura for now), 2.6 GHz 6-Core Intel Core i7 MacBook Pro
What did you do?

• Debugging with breakpoints was working with dlv, go, and MacOS Ventura until upgrading to Sonoma.
• Using a very simple go file (see session below)...
• After ugrade, in VSCode setting a breakpoint seemed ok, but running would appear to hang. Upgrading VSCode showed errors:

     unexpected fault address 0x10ad4c0
     2023-11-05T21:52:06-06:00 error layer=dap runtime error: EOF
     Unable to retrieve goroutines: write tcp 127.0.0.1:53046->127.0.0.1:53048: write: broken pipe

• tried "debugAdapter":"legacy" in settings, then errors displayed in VSCode are:

     unexpected fault address 0x10ad4c0
     Failed to continue - EOF
     Unhandled error in debug adapter: UnhandledPromiseRejection: This error originated either by throwing inside of an async 
```function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason "EOF".

• tried dlv command line, then errors are:

     Command failed: EOF
     could not detach process 45204: write tcp 127.0.0.1:52722->127.0.0.1:52723: write: broken pipe

What did you expect to see? Hit breakpoint without without error
What did you see instead? In VSCode, the dap did not communicate. With dlv command line, continue first time fails to break, and continue again displays broken pipe. However, not setting a breakpoint allows process to complete.

• I also tried re-installing Xcode after finding a 2019 bug report with similar symptom
• other people in my organization running Sonoma do not have this issue. Could it be some go configuration I need??

Here is the command-line session with a simple file:
