Hey @blueprintnotfound!
The error you are receiving suggests you are having issues with your graphics driver. A common fix for this issue is to go into NVidia Control Panel and reset the global defaults. There may be a setting active or error that is making Unreal unable to function.
Here are the instructions to do so. These instructions come from Nividia and not from Epic Games:
- Right-click on your desktop and select Nvidia Control Panel.
- Click Manage 3D Settings.
- Click the Global Settings tab.
- In the upper-right corner, click Restore Defaults.
I hope the above solution works for you!
