D3D11Util.cpp] [Line: 393]

Has anyone experienced this? As soon as I click around to start making a new project on UE5.0.3, I receive the following error. Everything is installed on the C:\ drive so I have no idea why it’s even looking in another drive in the first place. Do I need to write something out in a config file somewhere?

Problem Solved: Went to Nvidia site and downloaded driver packages that pertain to my card and then uninstalled the video card through the Device Manager. Then just reinstalled the driver with the one I downloaded. Must’ve been an issue with Nvidia’s latest drivers or they were installed/configured improperly.
