Looks weird. It seems the user is running a 4.1.5 binary... The binaries bundle both sip and PyQt5.QtMultimedia, and (at least when I test, but also for the majority of users I guess) the bundled versions are compatible with each other... So how could this user have incompatible versions?

[SomberNight]

Ah, maybe this is related to #6748
If the user is using the setup exe, and installed (upgraded) Electrum while it was already running, all kinds of madness might ensue.
