P3Dv5 HF1 CTD: nvwgf2umx.dll [SOLVED]

Featured Replies

I was on 466.XX version of Nvidia Driver, and wasn't having P3D load up, so I rolled back to my previous version, but still won't load. Attached is the Windows log: 

Faulting application name: Prepar3D.exe, version: 5.1.12.26829, time stamp: 0x5fb44f72
Faulting module name: nvwgf2umx.dll, version: 27.21.14.6589, time stamp: 0x605cd9e9
Exception code: 0xc0000005
Fault offset: 0x00000000001b1643
Faulting process id: 0x3508
Faulting application start time: 0x01d737099a10da23
Faulting application path: D:\Prepar3D v5\Prepar3D.exe
Faulting module path: C:\WINDOWS\System32\DriverStore\FileRepository\nv_dispi.inf_amd64_cc5a8fceed9bb371\nvwgf2umx.dll
Report Id: a3d4533d-ab91-48da-a3c4-f9a3e01dff19
 

SOLVED: Rolled back two versions of the driver: works now.

In my case, neither driver 466.11 nor 465.89 worked for me.
By rolling back to 457.30, the Scenario page can load without a CTD.
 

Edit: Ah, it's a known issue.
