I believe this is a duplicate of:

• MSB4181: The "Restore Task" task returned false but did not log an error. #13460

You appear to be using .NET 9 preview 5, which is quite old, apparently released on the 11th of June, which is the same day as the fix got merged into Nuget.Client. Therefore, I suspect if you upgrade to a newer version of the .NET SDK, you should receive error messages when the error scenario happens.

We have multiple issues tracking that bug, what @zivkan linked and then a newer bug: #13545.

It was fixed and the linked dnceng issue was also referenced in #13545 (comment).

I'm gonna close this as a dup.

Please let us know if this persists in latest .NET 9 SDK previews.
