This has three failures, all on MacOS. We get the following values in place of the magic word (one log is missing):
0x70202020200a3b6d
0x40066db4005595be

These don't look anything like the ones we're seeing in the wild on crash stats.

It seems this crash no longer occurs since I cant find any reports on it , I will close it as WFM and then if it starts to reoccur we can reopen the issue
