❔ update-package : Failed to add reference to 'xyz'. Error HRESULT E_FAIL has been returned

So I don't really know what happened. Turned my pc on, opened a project I created 2 days ago. My pacakges.config file was missing and was like ok weird. Made nuget recreate it and realized my references were gone so forced a reinstall through nuget. Now, for whatever reason I keep getting failed HRESULTS. It isn't specific to discord.net, it happens to random packages the more I retry, it just picks a random package to error. I have tried to delete the nuget cache, nuget.config file and I have also ran the command that is meant to fix the problem gacutil -i Microsoft.VisualStudio.Shell.Interop.11.0.dll but no luck. I have both VS 2022 and 2017, both of them seem to return the same exact issue now. I'm not sure what happened but I think a cache is corrupt? I just don't know which one...
I have tried to create a new project with .net framework console, tried different versions ranging from 4.6-4.8 and still the issue persists. I'd only have to assume it would be the same for .net core.
Here is the error I get

update-package : Failed to add reference to 'Discord.Net.Core'.

Would love to know if someone has managed to fix this before because this is the first time It has happened to me. Very frustrating 😦 It doesn't seem to matter what VS I use, be it 2017 or 2022, it gives the same issue even if I create a new project on both VS's separately.

packages.config? that's only for pre-SDK projects, which only exist for .NET Framework, and I'd hope you wouldn't be using Framework for a Discord bot (or anything at all really) you should be using .NET 7, which uses SDK projects, which use PackageReference the Discord.Net docs specifically recommend .NET 6 or later
