Zoom recording ended abruptly. Now I only have the second half recording... gone for good?

I was recording a meeting yesterday and half way through the meeting, the recording ended abruptly. I re-started it but zoom only converted the second half and not the first. I am 1000% sure i was recording. I had the save to local device option checked. Is the recording lost forever? I dont see it in the folder where the second half was saved and dont see another folder either.
