Provide a minimal init.vim/vimrc without plugin managers (Required!)

const s:plugin_dir = '~/.cache/dpp/repos/github.com'->expand()
const s:plugins = [
  \ 'vim-denops/denops.vim',
  \ 'Shougo/ddu.vim',
  \ 'Shougo/ddu-ui-filer',
  \ 'Shougo/ddu-kind-file',
  \ 'Shougo/ddu-source-file',
  \ 'Shougo/ddu-filter-matcher_substring'
\ ]

for p in s:plugins
  execute $'set rtp^={s:plugin_dir}/{p}'
endfor

call ddu#custom#patch_global(#{
  \ ui: 'filer',
  \ kindOptions: #{
    \ file: #{
      \ defaultAction: "open",
    \ },
  \ },
  \ sources: [
    \ #{
      \ name: 'file',
      \ options: #{
        \ matchers: ['matcher_substring'],
      \ }
    \ },
  \ ],
\ })

function! s:keymaps() abort
  nnoremap <buffer> <CR> <Cmd>call ddu#ui#sync_action("itemAction")<CR>
  nnoremap <buffer> q <Cmd>call ddu#ui#sync_action("quit")<CR>
endfunction

augroup filer
  autocmd!
  autocmd FileType ddu-filer call s:keymaps()
augroup END

command! Test call ddu#start()

How to reproduce the problem from neovim/Vim startup (Required!)

1. Start the editor.
   • Neovim -> nvim -u init.vim
   • Vim -> vim -N -u init.vim
2. Start filer.
   • :Test
3. Perform any action
   • Open file with <CR>
   • Close ui with q

The editor will freeze and won't accept any operations!

Fixed. Please update ddu.vim.
