neovim adds ^M at the end of the after saving

Question

I'm new to using neovim so pardon me if the fix is too obvious.

The issue that I'm having is that if I create a file using the command.

nvim file.txt

and then edit it let's say something like this

hello

then save it with :w the file will show as the following

hello^M

I tried the command :set ff=unix but I does not work. I think the issue is the init.vim which I took from https://github.com/craftzdog/dotfiles-public

and modify it to not use fish as a terminal, the code is the following.

Quick note It appears that the issue only happens when is a .tsx file

I finally found the culprit. It was prettier, I remove it from the lspconfig.rc file as a temporary solution please let me know if you why this was happening
