Folders randomly close when working in Go submodule, added as separate top-level folder

[distinctdan]

Issue Type: Bug

I have a Go project that has the following structure:

project
    <some files>
    subfolder
        <more files>
        go.mod
    go.mod
subfolder

VSCode recommends that I add the subfolder as a separate workspace folder in order for go autocomplete and error highlighting to work. However, when I do that, vscode starts behaving badly. In the Explorer pane, my open folders will randomly close. If I'm in the middle of creating a file, it cancels editing the name and saves it as is, which is pretty obnoxious. It's almost like the pane is resetting.

So to summarize the issues:

• VSCode shouldn't be randomly closing folders
• It shouldn't require me to add a subfolder as a separate top-level workspace folder (this issue may be with the go tooling rather than vscode itself.)

Thanks for the help

Thanks for submitting this issue. Please also check if it is already covered by an existing one, like:

• Sometimes folder cannot be selected in VS Code Explorer (#110727)

Does the random closing also happen with all your extensions disabled? One way to investigate this is to run the Start Extension Bisect command and follow its instructions.

[distinctdan]

Thanks, I started the extension bisect, and the issue still happens on the very first step, which it said means it's a problem with vscode. Here are the specific steps I took:

• Double click a file in the main project
• Expand the top-level subfolder
• Don't click anything else and wait ~10 seconds
• The subfolder will close on its own

I can not reproduce on my machine. Might you have some file generating task in the background?
Can you reproduce with vscode insiders https://code.visualstudio.com/insiders/

[distinctdan]

I don't think I have any file generating stuff going on. I'm usually running a webpack server, but I've never seen that trigger anything in the Explorer pane when it rebuilds.

[distinctdan]

I'm sorry, but I'd rather not switch to using insiders. That's unfortunate that you aren't able to reproduce it.
