TEXT DIFF (though the test seems to fail with different messages each time):

 CONSOLE MESSAGE: A MediaStreamTrack ended due to a capture failure

REPRODUCIBILITY:

I was able to reproduce this issue constantly on macOS Ventura (13.5, 22G74/x86_64) WK2 debug at 267085@main using the following command:

run-webkit-tests --clobber-old-results --debug --verbose --iterations 50 fast/mediastream/device-change-event-2.html

REGRESSION:

I was unable to locate a regression point; however, according to the related issue, this issue (or similar) has existed since 225536@main.
