描述

bug Release0.85
Problem Description

Selecting text that includes Japanese characters displayed in , turning on the Japanese IME, and typing any character causes an immediate crash.

Steps To Reproduce
  1. Type into the TextInput
  2. Select text that includes Japanese characters
  3. Turn on Japanese IME
  4. Type a single character
  5. The app crashes with the following log: INFO Connection established to app='TextInputCrash_1.0.0.0_x64__2f65sjwpnhfvw' on device='TowerPC'.
    I tried both Copilot Keyboard and Microsoft IME, but both showed the same behavior.
