Fzf commands (:Files) open new shell process in Git-bash Windows

[TheNoble6]

• [x] I have fzf 0.23.0 or above
• [x] I have read through https://github.com/junegunn/fzf.vim/blob/master/README.md
• [x] I have read through https://github.com/junegunn/fzf/blob/master/README-VIM.md
• [x] I have read through the manual page of fzf (man fzf)
• [x] I have searched through the existing issues

:Files/:FZF in vim within git-bash shell is opening new sh.exe window instead of within vim window.

I tried setting fzf_layout in .vimrc (as in Fzf Vim Readme: let g:fzf_layout = { 'down': '30%' } ) but still getting same behaviour of new shell process in new window, while vim display goes blank

Expected behavior: fzf search window opens within same vim process

I'm having the same issue @TheNoble6.

The only workaround I found was to instead run Vim in a Windows Subsystem for Linux (WSL) distribution. However, this isn't great, because there are serious performance problems when accessing directories on your Windows filesystem (present within WSL at /mnt/c/path/to/your/project). It might work ok for a very small project, but with a few tens of thousands of files, each time I run :Files it takes around a minute to index them.

Using neovim instead of vim on Windows produced different results ... instead of the search appearing in a new window, the preview pane of :Files was empty.

Were you able to find a better workaround or fix for this issue?
