App crash when stop RTMP stream with vlc-unity on Pico neo 3

Summary

I used VLC-Unity to play RTMP streams on Pico neo 3. There are two things that can cause an app crash:

closing Njinx or FFMPEG before stopping play stream (MediaPlayer.Stop()) will cause a crash;
Pause (MediaPlayer.Pause()) and then stop (MediaPlayer.Stop()) when playing stream.

Minimal project and steps to reproduce

1.Use njinx and ffmpeg to build a rtmp stream;

2.Create a Unity Project with Pico SDK;

3.Import VLC-Unity, add ExampleVLCPlayer, add Open button and Stop button;

4.Build and run on pico neo 3, start rtmp stream, click play button;

5.stop rtmp stream, then click stop button;

6.app crash, can use Unity Android Logcat see error message.

What is the current bug behavior?

when mediaPlayer.Stop(), app crashed.

What is the expected correct behavior?

The app should not crash when stop play stream.

Does it work on other plaforms? Does it work with the official VLC apps?

This error does not appear on Android phones, Windows, or UWP platforms.
