Local Recording corrupted

I recorded an important ~2-hour interview using Zoom on my MacBook. After recording, I clicked to convert the recording. As it was almost done, I accidentally closed the room, which triggered another conversion window.

After the conversion finished, I found both the audio and video files saved locally. Both are the full length (~2 hours), but they become corrupted at minute 25 (audio) and minute 27 (video), the video/audio either freezes or becomes unplayable beyond that point.

In the folder, I also found a "recording.conf" file, but no other files.

I have 32GB available of local storage, so it cannot be storage problem.

Is there a way to repair or re-convert the original recording? Can the "recording.conf" file help? 

Any advice would be really appreciated.
