I'm having the same problem, with a core dump of kscreenlocker at the end (I
woke up this morning to find the "Screen locker is broken..." message). Anyway,
here are more info and my own conclusions at the end.
The following tests were made with plasma 5.16.5 on a Manjaro system with the
BreezeDark screen locker and VLC with a media loaded (playing or paused). It
does the same with Clementine or other media players.

>From what I could understand the core dump is caused by the failed attempt to
resize the media image for the lock screen. I have identified this commit as
the issue:
https://github.com/KDE/plasma-workspace/commit/953f72e42f6c30ff951570ca53bc3c7a859aa5bc.
As a further test, I removed the committed line from
/usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/MediaControls.qml
and the problem disappeared.
