I was able to reproduce the crash locally on my device running iOS 18 Simulator Debug ToT using the following command: run-webkit-tests http/wpt/mediasession/gpuProcessCrash-voiceDetection.html --ipad-simulator

Referring to the history, it is shown that the tests were failing somewhere between 299127@main and 297215@main. Using reproduction steps above, I found that the tests were passing at 299127@main, but failed at 299128@main. At this time, I believe that the regression point is 299128@main.
