The

[keys.normal]
C-/ = "toggle_comments" #nope

case is expected: that's invalid TOML.

It looks like the terminal or crossterm are a bit confused about the C-/. Using crossterm's event-read example:

Event: Key(KeyEvent { code: Char('/'), modifiers: NONE })
Event: Key(KeyEvent { code: Char('7'), modifiers: CONTROL })

It's interpreted as C-7 🤔

I think this falls under #1085
