(5.4.4) Compile Errors: numerous "Failed to restore" ..."*.csproj"

Hello,

I found the answer to my question whilst writing this up, so thought I’d post it here in case anyone else has something similar in the future.

The solution can be found here: https://learn.microsoft.com/en-us/answers/questions/1343108/nuget-error-nu1101

Please click Tools > NuGet Package Manager > Package Manager Settings > Package Sources > check if nuget.org package source has been added. If it hasn’t been added, please click the “Add” button on top right corner > change the Name to nuget.org and the Source to https://api.nuget.org/v3/index.json > click Update > click OK, then rebuild your project.

After a fresh install of UE5.4 and VS2022 Community the following errors appeared when I compiled, ending in:

========== Build: 1 succeeded, 10 failed, 1 up-to-date, 0 skipped ==========

A VS popup opened, stating, “There were build errors. Would you like to continue and run the last successful build?”

However, if I selected “Yes”, UE5 starts, and the class I’ve added is available to make a BP from.

Here’s what I have installed from VS2022 - I followed Epic’s Setting Up Visual Studio guide, and still had the above issue
