MediaRecorder second time recoriding prepare failed w/ Camera2

I have been struggling for some time now on why I am not able to record for a second time with MediaRecorder. Every time I try it says:

Caused by: java.io.IOException: prepare failed.

I am not sure what I am doing wrong and frankly I have been staring at this for too long. I am doing this in Kotlin, but for the most part it is the same as Java with the exception of the function syntax. Please can anyone help? I have looked at others and the camera2 and mediarecorder being implemented, but it isn't working.

Start by reproducing the second-recording failure and trace the MediaRecorder setup and cleanup around the Camera2 code shown in the issue. Compare the recorder and camera state before the first and second calls to prepare; done means recording can be started a second time without the IOException.
