The best solution is singular ''they. ''It's a preexisting pronoun in English which is used for cases of unknown or immaterial gender. There are some ambiguities with it, but none that don't already exist given its long history in the singular. English already faces a similar issue with you, and while there may be some changes in the works there, it's uncomplicated enough.
