LGTM, the failure on test-ubuntu-24.04-cpp-thread-sanitizer isn't related but I haven't seen it anywhere else yet and I just triggered the cpp jobs on a different PR where all are green. It hasn't failed on the nightlies yet. Maybe is related to a commit on main, my PR isn't rebased to latest. I'll keep an eye for further failures on the job.
