Failed to save part of the recording

[viviotitto]

Guys please help me if I have any hope.

OBS haven't saved the part of the quite important talk, there is only 15 mins out of 30 and two log files. One contains the recording path and the other one doesn't have it.

Are there any temp files i could try to retrieve the audio, or is it just completely lost?

The programme was unresponsive and then just closed after the warning from windows.

OBS does not record to temp-files, it records directly to the output file.
From those logs, it appears you recorded one time, for almost exactly 30 minutes before attempting to start streaming, then exiting OBS.

When playing back the file C:/Users/V/Videos/2021-01-21 14-12-57.mkv in VLC (not the default 'Movies and TV' player that comes with Windows), what does it show? Only a 15 minute long video? Is audio 'lost' after 15 minutes, and just muted? Is the video also lost?
