Disassembly of libdispatch.dylib`_firehose_task_buffer_init confirms the "BUG IN LIBDISPATCH: Unable to get the unique pid (size)" occurs after its call to proc_pidinfo fails. Adding ```(allow process-info-pidinfo (target self))``` to the utility sandbox policy (used by the RDD process) avoids the crash and allows AV1 decoding to work in my limited testing so far.
