&gt; What are you doing when this crash happens? The backtrace doesn&apos;t involve
&gt; any KDE code, so it is very likely a bug in Qt itself.

I don&apos;t know exactly what could have triggered the crash: Plasma was running in a virtual machine I was using Zoom + modifying some audio settings when Plasma crashed</thetext>
