Lsp.stop stop tsserver end eslint

Hello everyone,
I have followed the video "0 to LSP : Neovim RC From Scratch" to setup my rust light saber (Thank you so much ThePrimeagen).
However, the config is causing tsserver and eslint to stop. If anyone have the isssue with tsserver and eslint got detached everytime you navigate with telescope or open new buffer, please comment those line. This is a temporary fix because I am not experience with neovim config. If you have a proper solution, please point out for me

  if client.name == "eslint" then
      vim.cmd.LspStop('eslint')
      return
  end

Start by reproducing the issue while navigating with Telescope or opening a new buffer, then inspect the Lua LSP configuration around the shown client.name == "eslint" conditional. Confirm whether tsserver and eslint detach, and consider the issue done when both remain attached during those actions without relying on the temporary LspStop workaround.
