Describe the bug
Failed to execute :Bdelete! to close lazy-lock.json file, when set ttyfast option, there's an error:

To Reproduce
use lazy.nvim install bufdelete.nvim plugin, and set ttyfast in init.vim, open lazy-lock.json file, then :Bdelete! to close it.

Expected behavior
Close correctly without error message.

Does this error occur in the minimal init file?
Use the following commands to download the minimal init file provided by bufdelete:
curl -fLO https://raw.githubusercontent.com/famiu/bufdelete.nvim/master/minimal_init.lua

Modify the file to your needs (if necessary), then load Neovim using:
nvim --noplugin -u minimal_init.lua

And check if your issue still occurs.

Provide modified minimal_init.lua
If you modified the minimal_init.lua that bufdelete provides by default in order to fit your configuration, put it here. Otherwise ignore this part.

Screenshots
If applicable, add screenshots to help explain your problem.

Additional context
Add any other context about the problem here (eg: other plugins that may conflict with this plugin, configuration options that you think might cause the issue, etc.).
