Crash to desktop

[Baahb3]

In the past couple weeks, I have had an increasing number of crashes to desktop.

Event ID 1000

Faulting application name: dndclient.exe, version: 4400.48.6210.4003, time stamp: 0x5dcc9572
Faulting module name: dndclient.exe, version: 4400.48.6210.4003, time stamp: 0x5dcc9572
Exception code: 0xc0000005
Fault offset: 0x004ec39b
Faulting process id: 0x3b2c
Faulting application start time: 0x01d5a87826973c80
Faulting application path: C:\Program Files (x86)\StandingStoneGames\Dungeons & Dragons Online\dndclient.exe
Faulting module path: C:\Program Files (x86)\StandingStoneGames\Dungeons & Dragons Online\dndclient.exe
Report Id: bfa48fd9-aba2-4ee7-9e7f-be3fc7759e8f
Faulting package full name:
Faulting package-relative application ID:

I started with making sure my graphics drivers were up to date.
I have also tried in Full Screen, Full Screen Windowed and Windowed mode. Happens in all modes, though seems more frequent in Full Screen (Windowed).

Resolution 2560x1440
DirectX11
Win10 Pro

Checking the event viewer for each crash, they mostly just report a basic App crash for dndclient.exe. One of them pointed to a specific *.dll file, umbra.dll.

Digging through the *.wer files for a couple of the crashes:

Sig[3].Name=Fault Module Name
Sig[3].Value=dndclient.exe
Sig[4].Name=Fault Module Version
Sig[4].Value=4400.48.6210.4003
Sig[5].Name=Fault Module Timestamp
Sig[5].Value=5dcc9572
Sig[6].Name=Exception Code
Sig[6].Value=c0000005
Sig[7].Name=Exception Offset
Sig[7].Value=004ec39b

Before I start playing around with my shadows setting in game, I wanted to check and see if someone at SSG had some better understanding of that *.dll and what it controls, and perhaps what the exception codes are pointing to.

Full *.wer file can be provided if necessary.
Thanks in advance for any assistance.

Try running in DirectX 9 and see if that helps.

Thanks, will give that a shot. I'll update after a couple days.

No crashes since changing back to DirectX9. Thanks for the suggestion.
