Meeting Recording Did Not Fully Convert

Hello. I recorded a zoom meeting yesterday locally and like the above i got confirmation of the recording (the vocal prompt and the recording in top left) I had to leave after i froze and came back and repeated the record process.  Both times i was told there was an error in converting and i could still convert, which is did-but i did not convert in whole.  I have both the meeting recording folder, but the video is super shot (3 mins for the first 20 mins and like 3 seconds for the other. When i do the double click to convert nothing happens and i followed the process to open the bin folder and open the zTscoder.exe and nothing.  Via the Zoom client they only play the short lengths. Are these recording gone?
