Wireless Display Option Doesn't Work.

[farxone]

Hello
I'm currently on Stable 8.5.3.0 but I had the same problem with previous releases.

When I try to launch the option "wireless display" for screen mirroring, immediately I get the message "Unfortunately, Wireless display has stop ...".

Here is the beginning of the associated error message :

"java.lang.RuntimeException: Unable to start activity ComponentInfo {com.xiaomi.miplay/com.xiaomi.miplay.ui.DeviceListActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'android.hardware.display.WifiDisplaySessionInfo android.hardware.display.WifiDisplayStatus.getSessionInfo()' on a null object reference"

with 50 lines more.

I do not know what that means.
Can anyone help me?
