I run into the same issue and used the following method to fix it. Hope this helps.
- Open language setting from language bar. A window called "Microsoft Pinyin" pops out
- Go to "General"
- Scroll the mouse all the way to the end
- Toggle to "On" to "Use previous version of Microsoft Pinyin"
Note: This might not be the way you want to fix the issue as it lost all new features from the updated version
