Remove comment when starting new line

[kasshedi117]

Actually if I have a comment in Lua file for example

-- comment.setup [myCursor] {}

from that line when I press 'O' to start typing in insert mode next line i got this

-- comment.setup {}
-- [myCursor]

instead I want to have

-- comment.setup {}
[myCursor]

without adding comment to the next line, thanks in advance.

This is a builtin feature of nvim, you can control it by tweaking the formatoptions option, see :h formatoptions and :h fo-table.

It's common that this option is overwritten by filetype runtime plugins, in which case you'll need to change it back the way you want.
For example for Lua, you can get your behavior like this:

" In ~/.config/nvim/after/ftplugin/lua.vim
" (to make sure it is run after $VIMRUNTIME/ftplugin/lua.vim which is loaded for every Lua file)
setlocal formatoptions-=o

o   Automatically insert the current comment leader after hitting 'o' or
    'O' in Normal mode.  In case comment is unwanted in a specific place
    use CTRL-U to quickly delete it. [i_CTRL-U](https://neovim.io/doc/user/insert.html#i_CTRL-U)
