Bump, facing a similar issue with sqlalchemy.sql.elements.quoted_name. I don't know one iota of Rust, but I wonder if this check here:

orjson/src/serialize/dict.rs

Line 73 in acaecd2

if unlikely!(unsafe { ob_type!(key) != STR_TYPE }) {

could be made so it checks if the key is a subclass of string.
