I wonder why? Thank you! error C2079: '_' uses undefined struct 'fmt::v10::detail::type_is_unformattable_for<T,char>' error C2338: Cannot format an argument. To make type T formattable provide a formatter<T> specialization: https://fmt.dev/latest/api.html#udt

looks like the source code for https://github.com/TheCherno/Hazel project that I have seen in several Issue (#1505, #3054) in the past. I recommend that you ask that question if it is a Hazel project issue.
