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")
}

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.

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!
