Scan for New Music crashes part way through

<-------------------------Subsonic Help Request---------------------->
Problem Description: New Music not appearing - turns out scanning process is crashing part way through

I am prepared to believe that the cause of the problem is a damaged or faulty music file, but I cannot find out how to identify
the problem file. All recently added music files were labelled using Media Monkey without any problems.

Troubleshooting Steps: Manually re-running scan (no change). Viewed subsonic log file - scan crashing - see below
Playback Application and version: Sonos Version 9.2
Subsonic Version: 6.1.4 (build c43f63) – November 11, 2018
Server Version: jetty-6.1.x, java 1.8.0_152, HSQLDB, Windows 10 (71.7 MB / 145.0 MB)
Hardware Platform: Windows 10 Pro
Java Memory Limit: Not sure ... see above
Problem Filename: Don't know
Output from ffmpeg -i: Don't know how to do this - possibly not relevant
Last ten log file lines: I have included rather more than this, I think the extra is relevant
