Is this related to https://bugs.webkit.org/show_bug.cgi?id=231444 and many others? These are almost identical outputs with the exception of this line:

08:54:36.668 7677 worker/3 This test marked as a crash because of no data while reading stdout for the server process.
08:54:36.669 7677 worker/3 This test marked as a crash because of no data while reading stdout for the server process.

These always 'fail' due to 'GPUProcess crashed'

[Eric Hutchison]

Unable to reproduce on ToT on iOS15.

Also, these tests can be seen with the same output across Catalina, BigSur, iOS14 and iOS15.
