Core Machine (Operating system/System info/Roon build number)
Win10Pro Core Machine:
i9 9900k
64GB DDR4 RAM (4200mHz, 4x16GB)
2x GTX 1080Ti
That’s everything I thought pertinent. Music storage is in several locations, Tidal & Qobuz integrated. Usually fed by my NAS but currently being fed by my 14TB external hard drive until I get around to doing some maintenance (unrelated, has been fed by external hard drive for the better part of 2021 with no issues)
Network Details (Including networking gear model/manufacturer and if on WiFi/Ethernet)
Everything has custom length ethernet runs going to it. Currently I have the Pi2AES on WiFi (a dedicated 5GHz band) as I was troubleshooting.
Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/etc.)
N/A.
Description Of Issue
The thing wont stay open for more than a few minutes to test different audio devices. When I see it load however it’s my default group containing my Pi2AES which feeds my Holo May and my Soncoz SGD1, as well as a virtual audio driver which is used to feed my VU’s and Visualizer. Should be noted I have switched to just use Pi2AES direct instead of feeding it to HQPlayer, again for troubleshooting. I also feel it pertinent to note that of these two devices I have also attempted launching Roon with both devices disabled / powered down, again unfortunately with no luck.
Some time last night as I was doing a listening session (always groovy, complete Roon convert here, btw please update API I love tinkering 
) Roon crashed suddenly and without warning, my first assumption was it didn’t like how much I was skipping around, though I haven’t had issues skipping chunks of playlists before, though it did skip 4,000+ tracks without issue and continue trucking so unsure if that’s the root cause.
After the application crashed, and to simplify troubleshooting steps (day job in IT Architecture, I usually don’t end up making posts, but I’m at my wit’s end…) here’s what I have done so far:
-
Checked with UAC enabled and disabled, no change.
-
Checked with firewall enabled and disabled, no change. Don’t think either of these are applicable to my issue as the app is crashing, not some other functionality.
-
Checked event viewer, latest logs indicate issues with loading ntdll.dll, which is used for NT kernel functions to the best of my knowledge.
-
Thus I ran an SFC scan to be sure, as I have other applications that utilize that dll file and none have had issues initializing it, and as the title suggests, the latest changes to my OS were a Windows update to bring me to latest version a few weeks ago, followed by the Roon update not long after. For the record, SFC scan showed no integrity violations
-
Rebooted a few times, rolled back windows update, reinstalled windows update. Again, all no change.
-
Checked Roon logs a few times, nothing there really stood out to me but I did catch that it failed to initialize my external hard drive that I’ve been using to troubleshoot, I also tried mapping it as a networked drive and disconnecting USB, no change.
-
Again of note, it stated drive availability is false, I have other backups run to that drive weekly of my various git forks with no issues, so I found that strange:
Here is a snippet of that info log that jumped out to me:

That is my hunch as to what may be the issue…
–Proofreading edit–
Scratch the above…upon further inspection looks like after the GET request it reinits and shows the drive is attached and available:
