Grep search does not work when on windows UNC path

[Zbychomir]

Description

When I open Neovim while being on a network path (for example, \\SERVER01\d$\directory) and try to search using Telescope's grep search, the operation fails.

[telescope] [WARN 13:38:52] C:/Users/my-user/AppData/Local/nvim-data/lazy/telescope.nvim/lua/telescope/pickers.lua:497: Finder failed with msg: .../Local/nvim-data/lazy/telescope.nvim/lua/telescope/_.lua:76: Failed to spawn process: { command = "rg", pid = "ENOENT: no such file or directory",

[...]

uv_opts = { [...] cwd = "\\\\servervm6\\d\\$\\net\\sites\\webapp}

I suspect that the problem is "d$" being split into "d" and "$", resulting in an invalid path.

Neovim version

NVIM v0.9.5
Build type: RelWithDebInfo
LuaJIT 2.1.1703942320

Operating system and version

Windows 11 Pro

Telescope version / branch / rev

telescope 0.1.x

checkhealth telescope

When starting Neovim on path C:\test:

==============================================================================
telescope: require("telescope.health").check()

Checking for required plugins ~
- OK plenary installed.
- OK nvim-treesitter installed.

Checking external dependencies ~
- OK rg: found ripgrep 14.1.0 (rev e50df40a19)
- OK fd: found fd 9.0.0

===== Installed extensions ===== ~

After changing path: :lcd \\DESKTOP-NAME\c$\test:
==============================================================================
telescope: require("telescope.health").check()

- ERROR Failed to run healthcheck for "telescope" plugin. Exception:

Steps to reproduce

1. nvim -nu minimal.lua
2. :cd \\YOUR_MACHINE_NAME\c$
3. :Telescope live_grep
4. Type text you are looking for

Expected behavior

Display list of files containing searched text and preview of selected file in Grep Preview section.

Actual behavior

"Results" and "Grep Preview" sections are empty. Warning appears in :messages
