Bug Description

Hi,
I am trying to connect from WIN10 to an Android IFP with Android 11.
The connection can be esteblished, but after allow on Android, on the Windows Client is a message "waiting for screen" and the screen is not shared.

I captured the log from Android and found the following messages:

03-24 11:48:24.621 2360 2360 E DartMessenger: Uncaught exception in binary message listener

A bigger log is attached.

rust-log.txt

I've tried it with different Versions (App-Store, Nightly-Build, self-build) and offical Server and selfHost-Server.
All combinations show the same result.

With an Android-Phone it works fine.

What can be the reason or soloution?

How to Reproduce

Run the client on an IFP

Expected Behavior

The screen will be shared to the other client

Operating system(s) on local side and remote side

Windows 10 -> Android

RustDesk Version(s) on local side and remote side

1.1.9 -> 1.1.9 , 1.2.0 -> 1.2.0
