It looks to me like this could be cross-talk between tests. I couldn't see what in these tests ensured that they used different project files, but that could just be that I am unfamiliar with the tests:

sdk/test/Microsoft.NET.Build.Tests/GivenThatWeHaveAPackageReferenceWithAliases.cs

I'm investigating this, and am experimenting in this PR: #39144

[dsplaisted]

Looks like I'm going to disable these tests for now: #39172

Closing in favor of #39172 as this is not tracking failures currently.
