dlv-dap fails to install for Go in VS Code on Windows for because of a malformed path

I am trying to get up VSCode in a virtual machine running Windows Server 2019 to allow debugging Windows-specific Go programs but when I try to compile and VSCode asks to install the tools it fails to install dlv-dap although installs the other tools fine. (I am new to VSCode and have not really used Windows in over 10 years, but have programmed for decades and in Go on macOS for several years now.)

The problem as you can see from the output is that bin has been duplicated in the go.exe path, e.g.:

C:\\Users\\Administrator\\go\\bin\\bin\\go.exe

I have reinstalled Go and reinstalled VSCode, I have moved around GOPATH and GOROOT, I have tried doing without GOPATH and GOROOT, I have added GOPATH and GOROOT to the settings.json file, and always the same problem.

This leads me to think this is a bug, but I wanted to make sure that it wasn't me doing something stupid before I reported it on GitHub, as they suggest in their directions for bug submission.

For this output I have these setting in my User environment:

• My GOROOT is C:\Users\Administrator\go\bin
• My GOPATH is C:\Users\Administrator\go

I also installed dlv-dap via command line outside of VSCode, but VSCode did not recognize that I had done so.

Any ideas what I might be doing wrong?

Also, where would I look for the source code that runs this install to see if I can determine if there is an error and if an error submit a pull request fixing it?

Thanks in advance for any help you might provide.

dlv-dap: failed to install dlv-dap(github.com/go-delve/delve/cmd/dlv@2f13672765fe): Error: spawn C:\Users\Administrator\go\bin\bin\go.exe ENOENT 
'C:\Users\Administrator\go\bin\go.exe env': warning: GOPATH set to GOROOT (C:\Users\Administrator\go) has no effect

And after all that, I removed go.goroot and go.delveConfig from settings.json, and it installed fine and just started working. (I had added those earlier while trying to debug the problem.)

This is what I removed from settings.json:

"go.goroot": "C:\Users\Administrator\go\bin",
"go.delveConfig": {
    "debugAdapter": "legacy",
}

I don't know if that "fixed" it, or if something else I did fixed it and that was just leftover cruft, but either way it is working now and hopefully this helps someone else that runs into the same issue.
