Unable to merge PR; Waiting for status to be reported

A repository to which I contribute has rules to prevent merging dev to master unless various checks are passed. This most recent PR for such a merge is blocked with “Waiting for status to be reported” on some of the tests.

We last did this shortly before the changes mentioned in “GitHub Actions update: Helping maintainers combat bad actors - The GitHub Blog” and everything ran as expected then.
Does anyone have any suggestions other than to disable these rules (which we’d rather not do)?
