This is a duplicate of this failure mode: #136800 (comment)
However, that issue got triaged under a different failure mode and was not revisited with this failure mode.

However, this is under shared-process:

Deployment mode: shared-process

so I will remove the release-blocker label on the assumption that this has to do with shared-process. (cc @kvoli).
