Thanks for the issue!

That error is an expected behavior. The reason is that executing :bnext means that you want to show another buffer in current (i.e. from 'mini.files') window. This doesn't make much sense from workflow perspective.

Also, I can not reproduce the error from the screenshot as it is most certainly not from the latest 'mini.nvim' (line 1515 does not contain any calls). On Neovim>=0.10 it should show something like "E1513: Cannot switch buffer. 'winfixbuf' is enabled". See #1173.

Closing as it is most certainly a fixed behavior.
