1 month ago I think the issue is related to https://github.com/junegunn/fzf.vim/issues/1543 in which it finds bash but it expands the path using cmd and gets a path separated with backlashes \ which bash (or vim) may not like.
I've built my own Rg command and this is how I built the preview
" find bash from git for windows
let g:bash = substitute(system('where.exe bash | awk "/[Gg]it/ {print}" | tr -d "\r\n"'), '\n', '', '')
" Transform bash path to use '/'
let bash_path = shellescape(substitute(g:bash, '\\', '/', 'g'))
" Path to preview script. The preview.sh file is the same as fzf.vim/bin/preview.sh with slightly modifications from my part.
" The MSYS style path '/c' is irrelevant here. Window style path works the same.
let preview_path = substitute('/c' . $HOMEPATH . '\scripts\utils\preview.sh', '\\', '/', 'g')
let command_preview = bash_path . ' ' . preview_path . ' {}'The preview command will look like this when executed by fzf.vim
^"--preview^" ^"\^"C:/Program Files/Git/usr/bin/bash.exe\^" /c/Users/user/scripts/utils/preview.sh {}^"The fzf#vim#with_preview() generates the preview as follows (before escaping)
'--preview', 'C:\PROGRA~1\Git\usr\bin\bash.exe C:/Users/user/.cache/vimfiles/fzf.vim/bin/preview.sh {}'The shorted path to bash is generated by passing the path to split(system('for %A in ("'. a:path .'") do @echo %~sA'), "\n")[0] which fzf.vim does internally and it always returns a backlashed path. If you change it to forward slash, it works.
An simple workaround is to manually add the preview arguments rather than calling fzf#vim#with_preview. What it does is to add the --preview argument and a toggle preview binding.
" instead of:
" let spec = fzf#vim#with_preview(spec)
" change to:
let spec.options = spec.options + [ '--preview', 'C:/PROGRA~1/Git/usr/bin/bash.exe C:/Users/user/.cache/vimfiles/fzf.vim/bin/preview.sh {}', '--bind', 'ctrl-/:toggle-preview' ]
call fzf#vim#grep(initial_command, spec, a:fullscreen)You may need to adjust the path to vim or parse the return of fzf#vim#with_preview. I didn't as I'm not very familiar with vim script.

Problem / Steps to reproduce
/bin/bash: line1: C:/Users/mindentropy/vimfiles/plugged/fzf.vim/bin/preview.shI check preview.sh and it has
#!/usr/bin/env bashbut I am not sure whether it is picking up bash. Is Rg supported on Windows 11?
