The lua-language-server not started while opening a .lua file from startup using nvim a.lua. :LspInfo showing 0 client(s) attached to this buffer.

But it works when switching to another .lua file: :e b.lua.

Only lua_ls with this problem. Other lsp servers (gopls, jsonls, bashls, pylsp) works well.

I use lazy.nvim and mason. Here's my lsp config. I can't figure it out. Anyone have any idea?
