[Other Issue] Nuget not being able to load sources

[mati23]

Description of issue

A few days ago I was able to assess one of my solutions successfully an was able to see the reports, incompatibilities and everything. Yesterday I tried again in the same project, without doing any changes to it, and after reaching over 70%, the build simply fails without any errors, and it doesn't create the reports anymore.

I tried to investigate running on Visual Studio 2022 and but after I run the Assess on tle solution, the task Activating Language Client: Porting Assistend for .NET times out.

I downloaded the project and try to run it, but the IDE fails to load the NuGet packages.
Some examples of outputs:

NuGet: Restore all packages in Solution
Restoring packages in solution PortingAssistant.Client
NotFound https://s3-us-west-2.amazonaws.com/aws.portingassistant.dotnet.download/nuget/flatcontainer/xunit.assert/index.json 736ms

NuGet: Restore all packages in Solution
Restoring packages in solution PortingAssistant.Client
Unable to load the service index for source https://dotnetfeed.blob.core.windows.net/dotnet-core/index.json.

I don't know if this is related to the reason why the assessment also fails in the Porting Assistant for .NET application (the .exe) but I don't seem to be able to run the tool by any approach.

I also tried deleting my NuGet.config file, but the result was the same after it gets recreated.

Additional context

Running dotnet nuget list source command, the output is this:
