Tests not passing: TestStatsReporter Flush not flushing

Expected Behavior

I'd expect running ./gradlew test or build would pass on a clean main branch. That is not happening.
WorkflowFailedMetricsTests.java runs a @Before setup that contains: reporter.flush()
Some methods are experiencing failures when ran in conjunction with other tests, such as:

Steps to Reproduce the Problem

1. Run ./gradlew build, or ./gradlew test

Start by running ./gradlew test or ./gradlew build and inspect TestStatsReporter.java, especially flush() and assertCounter(), alongside WorkflowFailedMetricsTests.java. Reproduce the failures at the reported test methods and determine why reporter.flush() does not make the expected metrics available. Done means the affected tests and the clean build pass consistently.
