I am experiencing the same issue, but in my Plex music library. The Plex Web player (version 4.74.2 according to my Settings) crashes and not always between tracks–it often konks out in the middle of playing a track.
I am also running the Plex Media server version 1.25.5.5492 on a WD PR4100.
At first I thought it was just a problem with the MS Edge browser, but I just verified that it crashes in Chrome too.
