Fatal Exception on Android 10

[IvanSheigets]

I tried to use VOICE_RECOGNITION and have next error:

 E/MediaRecorder: start failed: -38
2020-12-04 15:22:47.547 4602-4774/../AndroidRuntime: FATAL EXCEPTION: newRecordingThread
    Process:..., PID: 4602
    java.lang.IllegalStateException
        at android.media.MediaRecorder.start(Native Method)
        at core.recorder.core.android_recorder.MyMediaRecorder.start(

If change the audio source to something else there is no error but no voice record
