• SOS.StackTraceSoftwareExceptionFrame: Looks like a runtime change caused the frames present in the debuggees stack trace to change. I have opened a PR and put up test runs to verify the fix: Remove check from SOS test diagnostics#5582
• SOS.FindRootsOlderGeneration: I'm looking into why this is being flaky. Edit: FindRootsOlderGeneration refactor diagnostics#5585 will hopefully fix this issue.

Closing issue as resolved. I monitored the pipeline and the only remaining intermittent failures are due to the known issue: #117785
