Steps to reproduce

1. Install Plenary, Telescope and NrrwRgn,
2. Start nvim,
3. Type in text,
4. Select it in visual mode,
5. Run command :NR!
6. Ensure that there is only one window open with the NrrwRegion buffer inside it,
7. Try to run :Telescope files or any other picker,
8. You will get the error described above and Neovim will soft-lock.

Expected behavior

That it doesn't soft-lock the editor.

Actual behavior

You get an error like the following, and the editor becomes soft-locked:

Error executing Lua callback: ...avigation/start/telescope.nvim/lua/telescope/pickers.lua:580: Invalid buffer id: 4

You then have to run :qa! to exit and restart. The editor is rendered inoperable by the bug.
