I have looked at the crash dump and log files you provided here, as well as those you reported in another thread:
https://yabb.jriver.com/interact/index.php/topic,131452.msg914974.html#msg914974All three dump files point to a crash in Windows system file ntdll.dll and there is nothing that indicates anything in MC:
> ntdll.dll!RtlpWaitOnCriticalSection() Unknown
ntdll.dll!RtlpEnterCriticalSectionContended() Unknown
ntdll.dll!RtlEnterCriticalSection() Unknown
wdmaud.drv!CMixer::SendNotificationToWinmm(struct NOTIFICATION *) Unknown

AudioSes.dll!CAudioSessionControl::OnAudioSessionEvent() Unknown
AudioSes.dll!CAudioSessionControl::CAudioSessionNotificationDelegator::OnMediaNotification(struct MEDIA_NOTIFICATION_BLOCK *) Unknown
MMDevAPI.dll!CMediaNotifications::OnMediaNotificationWorkerHandler() Unknown
ntdll.dll!TppSimplepExecuteCallback() Unknown
ntdll.dll!TppWorkerThread() Unknown
kernel32.dll!BaseThreadInitThunk() Unknown
ntdll.dll!RtlUserThreadStart() Unknown
On the other hand, all three log files seem to suggest that the crash happened when MC was running WASAPI plugin:
43089691: 6112: Playback: CWASAPIPlugin::StartWASAPI: Started WASAPI: 9600 buffer blocks, 400.0000 internal buffer ms, 99 fill sleep ms, output format 96 kHz 24bit (padded) 6ch

43089692: 6112: Playback: CWASAPIPlugin::Thread: Starting
43089693: 6112: Playback: CWASAPIPlugin::Thread: Running feeder loop
Maybe there is an issue in your WASAPI driver?
