Start with the linked System.Perf_Convert.FromHexString history and report, then reproduce it with the benchmarks_ci.py command and the System.Perf_Convert* filter. Compare the baseline and test runs and inspect the referenced profiling or benchmarking workflow docs. The issue does not identify a source file or specify a change, so completion would require triage to establish the intended follow-up.
