This may be related to #54778.

This may also have been fixed by #54885? (Not clear to me whether that issue explains the hang in the test on darwin/arm64.)

No new occurrences since 2022-09-06T15:49:30-c35bc69/darwin-arm64-11, which I think is strong enough evidence that this was a dup of #54885, which has been fixed.
