Steps to reproduce:
1. Load Camila model (or any other high-quality model)
2. Apply any expression loop emotion to model (I tried happy and sad ones) using ExPlus
2.1. Editor will say that there some missing expressions in the model, but previously this was not a problem
3. Watch the animation

Expected result:
Emotion successfully animates full face of the character (including mouth)

Actual result:
Emotion animates only top part of the face, ignoring the mouth

Note:
Previously all worked fine. Recently I updated the OS version from Windows 10 to Windows 11 and changed the Character Creator version from 4.3 to 4.41

I can definitely say that previous setup worked fine because I have these expression loop emotions exported to my Unity project, and they working fine. The new emotion I exporting now don't animate the mouth.
