Render YUVJ420P is abnormal

[qqJoker]

I use Silk.Net and Avalonia.OpenGL to play the rtsp stream, and add three textures for rendering, but the problem is here, avalonia will occasionally appear the following error:

Avalonia.OpenGL.OpenGlException: Unable to make the context current

My rendering code is as follows:

protected override unsafe void OnOpenGlRender(GlInterface gl, int fb)
 {
        this._gl.Viewport(0, 0, (uint)Bounds.Width, (uint)Bounds.Height);
         //Get YUVJ420P Frame
        if (this._playerBase != null && this._playerBase.OutputFrameCache(this._uniqueKey, out var frame))
        {
            this._texture.Bind(frame, this._shader);
            this._shader.Use();
            this._vao.Bind();
            this._gl.DrawElements(PrimitiveType.Triangles, (uint)_indices.Length, DrawElementsType.UnsignedInt, null);
        }
       Dispatcher.UIThread.InvokeAsync(InvalidateVisual);
    }

Can you tell me what caused this error, thank you very much!!
