On this month’s Patch Tuesday event day, Windows 10 May 2020 (20H1/Version 2004) received a cumulative update of KB4565503. While bringing security updates to many system components and core applications, Microsoft lists a known issue in the update log: the Microsoft Input Method Editor (IME) in Chinese and Japanese that is not working properly.
“When using some applications, such as Microsoft Excel, Chinese an error may occur with the Microsoft Input Method Editor (IME) in Japanese, or the application may stop responding or closing when you try to drag with the mouse,” the support document reads. “
Microsoft says it is investigating the BUG and the current interim solution is as follows
1. Check Start, enter settings and return
2. Search input settings in the settings, select IME settings that match the language you are using, such as Japanese IME settings
3. Select General
4. Open microsoft IME using previous versions
