Start with Aspire.Hosting.JavaScript.Tests.NodeFunctionalTests.VerifyNodeAppWorks and the NodeAppFixture or DenoTelemetryFixture InitializeAsync path. Reproduce the failure on the Hosting.JavaScript windows-latest job from build 33802459402, then compare the two reported occurrences. Done means the Node/Deno functional tests no longer hit the one-minute initialization timeout on windows-latest.
