neovim adds ^M at the end of the after saving - vim

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

Answer 1

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
