My audio has cut out for no reason

I was recording the first episode of my podcast and after i had finished i noticed this track underneath of my voice that was filled with numbers and then when i would play that nothing would happen, so i essentially lost half of what i recorded and i don’t know why. I’m going to assume that this is an easy fix and i probably could have found this answer if i looked hard enough but here i am. I’m grateful to anyone that can help with this, thank you.

Is this problem still happening, or did it fix itself after a reboot?
