Invalid Public Identity Key - Minecraft Bedrock 1.16 beta

Hello there

Recently. After the new update, everytime i want to log in to a server in minecraft. A Invalid Public Identity key error appears on the screen. 

I was at 4G Network at that time so i changed to WiFi. Nothing changed. 

Any Troubleshooting steps for this kind of error? 

 

Device Information if needed :

Xiaomi Redmi 8 4/64 running on Android 9 - MiUi 11

Qualcomm Snapdragon 439 using Adreno 500 series
