Crashed: AURemoteIO::IOThread on AudioPlayer.setupEngine()

[vegetalu]

I have found crash on Crashlytics that says “partial apply for closure #1 in AudioPlayer.setupEngine() + 450”
The issue occurs sometime. Can you help me how to fix this issue.

This seems to be a crash regarding memory access violation, invalid pointers. Which is hard to pinpoint if it doesn't happen when debugger is connected.
