Problem with the Mimoji App

[Jimbo21]

I have a Xiaomi Mi 9 with the xiaomi.eu firmware. In the past, the Mimoji app always worked. Now it works under the firmware MIUI 11.1 by xiaomi.eu 9.11.7 no longer correct.
The selected Mimoji is always black. He reacts to my face, but the Mimoji is completely black. Does anyone have a solution or know why the picture remains black?

Same Problem with the xiaomi.eu 9.11.14 Firmware. Hope that the xiaomi.eu Team can fix the Problem with an Firmware Update.
