Had to clear my system of old Nvidia drivers, shaders, and files and I wanted a clean slate so I used DDU in safe mode and manually deleted any leftover Nvidia folders before rebooting. Everything ran smoothly and rebooting and reinstalling the drivers works just fine with one major issue: The Nvidia app doesn't work at all and I absolutely need it for Shadowplay and screenshots.

If I use the taskbar icon to boot it it pops up with a black screen and immediately closes.
If I run it via the shortcut as administrator it circles for like 10-20 seconds and then gives me this error.

I have already done every step I can possibly think of.
>I've uninstalled and reinstalled the app.
>Used an older version of the app to reinstall it.
>Done a full clean reinstall of the drivers with the official installer and with the "Clean install" option.
>Done a full clean reinstall of the drivers with the official installer and with the "Clean install" option with the app already installed.
>Used Nvidia's official cleaner app and did all of these steps.
>Gave ProgramData permissions.
>Set WpnService, WpnUserservice and WpnUserService_xxxx to '2' in regedit then rebooted.
>Turned off all the internet and tried booting it because some people said it might be failing to log in.
Nothing works. I've been at this like three hours now, I'm at my wits end. The logs don't point to anything being an issue either. Has anyone ever had to deal with this mess? Nothing people recommend works.
