Unable to use Delve to debug Go - Access is denied

Question

Attempting to use Delve to debug Go, I get the following error:

could not launch process: fork/exec C:\code\go_stuff\debugtest\__debug_bin: Access is denied.
could not remove C:\code\go_stuff\debugtest\__debug_bin: remove C:\code\go_stuff\debugtest\__debug_bin: Access is denied.

This is on a very simple Go project I created using go mod init and I wrote the main.go using Vim, so no VSCode or anything else is involved.

I tried to run dlv debug from the terminal and I get the above output. I also get the above output when I try and debug using Delve in VSCode as well.

I have tried this on another PC and it works perfectly so it may well be something environmental but I cannot fathom what is causing this.

None of the projects I am trying to debug are in git or indeed any other source control.

Before I incur any downvotes due to lack of code, here is my entire project:

package main

import "fmt"

func main() {
    fmt.Println("So we begin")
    fmt.Println("Here we end")
}

Actually I've met similar problem. I modify the "settings.json" file of VScode as following:

{
        "workbench.colorTheme": "Default Dark+",
        "workbench.editorAssociations": {
            "*.ipynb": "jupyter.notebook.ipynb"
        },
        "gopls": {
            "experimentalWorkspaceModule": true
        },
        "go.alternateTools": {
        
        },
        "go.delveConfig": {      
            "dlvLoadConfig": {
                "followPointers": true,
                "maxVariableRecurse": 1,
                "maxStringLen": 64,
                "maxArrayValues": 64,
                "maxStructFields": -1
            },
            "apiVersion": 2,
            "showGlobalVariables": false,
            "debugAdapter": "legacy",
            "substitutePath": []
        }
}

Then try to debug or either run without debug. It works and the "__debug_bin.exe" will not generate anymore. However I don't know the reason, it seems some problem of dlv configuration. Does anyone know the root cause? Hope this help you!

It seems to be have been an issue caused by anti-virus deleting the executable when I tried to run it or even debug it. I moved to developing Go in WSL2 using VSCode and I can debug the code without issue, so this would appear to be environmental and not an issue with either Delve or Go.
