Hi ROMC, maybe we have the same issue, and the fix work the same, but as leo said, it's maybe not WMP the issue, but maybe something else related to it, and uninstalling WMP stop the crash.
Maybe it's something corrupted in windows, or maybe it's related to hardware or software. can you tell which hardware component you have ?
i'm feeling a bit less "alone" here lol, but we're still only "two".
my computer is like this. I'm a musician and video editor, so my whole computer is built around this activity but i do other normal "stuff" with it. Office, 3D video software, Photo editing etc... (even if i had one or two video games installed, i don't and never play).
hardware : CPU I7-700 (not K).
Graphic card : Old Zotac GT 640 (Vga output on a CRT).
Soundcard : UR22 Steinberg.(not the MKII version).
Mini ITX motherboard Asrock H270M-Itx/AC
Avermedia TV HD 2 (usb Key to receive / Capture TV).
Keyboard : iRig Keys 37 Pro IK Multimedia (nothing to do with the crash, i only turn it on when i work in Cubase using a USB hub with switch on/off)
Seven CMC-Series Steinberg Controller.
a Wacom Intuos 5 Tablet Pen/touch as mouse.
A Counter Design Shuttle Xpress.
an Yamaha U1 Acoustic Piano with Midi feature (Usb Midi)
Main Software used are Vegas Pro 16, Sibelius and Cubase Pro 10.
Resonic player Beta as main mp3/Audio file player.
Lot of audio plugins + other software of all kind, Ilok and E-licencer installed.
see if my any chance you find a common point between my setup and yours.
DO was crashing as well with midifile, AC3 file, Wav (16 or 24 bits) so all the audio formats read by WMP. but No crash with Videos, no matter if videos are including Mp3, AAC, DTS or AC3 files, it was never crashing (video player : MPC-BE (it's an alternative version to MPC-HC). VLC is as well installed because it's used by some software, but i don't use it.
all the crash stopped when reverting to 12.12 or by removing WMP !
crashing with DO 12.1, 12.2, 12.3 and 12.4.
I use the last version of Windows 10 x64, that's mean i have the october 2018 update. i installed it immediatly when it has been available, despite all the issues which happened to lot of users (I never had one) and that made microsoft to delay the update for lot of users.
my system has not been re-installed since March 2017, i own a retail version of Windows 10 Pro, and it was a Clean and Fresh install, not an update from Windows 8.1 Pro.
I'm pretty sure (but can't confirm this) that if we reinstall Windows 10 from the beginning (and not as a repair system), the issue would go away (or maybe not) ahha !
