RESETTING MBOX 3 AFTER EXPORTING AUDIO IN CUBASE ELEMENTS 9.5.30

I load a project that I saved, then I go to FILE/ EXPORT/ AUDIO MIXDOWN. While the file is mixing down, the UI gets stuck then goes back to normal. After the process is done, I cannot hear any sound from my macbook pro WITH THE INTERFACE PLUGGED IN unless I unplug and replug the interface back up. I tried all the other DAWs I have and CUBASE IS THE ONLY DAW WITH THE SAID ISSUE.
