VLS info

vls version: 0.0.1.93767cb
vls server arguments: --child --socket --port 5008 --timeout 15

Problem Description

The VLS will install but breaks on language server startup. I have tried the following but ended up with the same fault.
A. Install via VSCode dialog box "VLS is not installed. Do you want to install it now?", V files open in the editor.
B. Install via VSCode dialog box "VLS is not installed. Do you want to install it now?", No V files open.
C. Install via v ls --install with and without open V files in the editor.

Fresh installations were made after deleting ~/.vls folder.
Restarting the language server does not help. The server failed immediately after startup.

Expected Output

That it is working.
