Bug description

Recently the app started crashing when using the default Apple Japanese keyboard. If I type and send a message, then attempt to start typing another message, the app crashes the second I press any key on my keyboard, preventing me form typing in a second message. I tested and it doesn't happen with the English keyboard.

Steps to reproduce

Set the iOS keyboard to Japanese
Type any message and send it to someone
Immediately attempt to press any key on the keyboard

Actual result: The app crashes

Expected result: I should be able to type in a message as normal.

Screenshots

Device info

Device: iPhone 7

iOS version: 15.7.7 (also happened in 15.7.6)

Signal version: 6.31

UPDATE: I figured out an other important detail

When typing with the Japanese keyboard, the text first enters into "compose mode", meaning the currently typed text appears "selected" and the keyboard offers a number of suggestions to replace the text with. This is how the keyboard invokes and embeds the Chinese characters, for instance.

If I Send a message while currently in this "compose mode", and then attempt to type in my second message, the crash happens.

If I press Enter to confirm my typed letters and turn the composed text into normal text, the app doesn't crash.
