I experienced the same issue on Samsung J4+, Android 9 Pie.

Fixed it by running mediaRecorder.start() and mediaRecorder.stop() in a Handler:

private val START = 0;
private val STOP  = 1;

inner class CameraHandler(looper: Looper?): Handler(looper) {

  override fun handleMessage(msg: Message?) {
    super.handleMessage(msg)
      try {
        when (msg?.what) {
          START -> mediaRecorder?.start()
          STOP  -> mediaRecorder?.stop()
        }
      } catch (e: Exception) {
        Log.d("debug", e.message)
      }
  }
}

declare the Handler:

private lateinit var mCameraHandler: Handler

initialize in OnCreate with a HandlerThread Looper:

val handlerThread: HandlerThread = HandlerThread("Camera Handler Thread")
handlerThread.start()
mCameraHandler = CameraHandler(handlerThread.looper)

when record or stop button is clicked call:

mCameraHandler.sendEmptyMessage(START)
mCameraHandler.sendEmptyMessage(STOP)

link to my messy code xD
