The linked BF involves the ValidateCollections hook trying to perform validation on collections that have already been dropped. More specifically, collections are dropped on the primary, and the oplogs of the drops are being applied on the secondary; but it looks like validate collection runs on the secondary before it knows that the collection has been dropped.

This looks similar to the fix in SERVER-90996. This suite creates a 2 node replica set but does not run CheckReplDBHash to ensure that the secondary has caught up. This ticket will add the CheckReplDBHash hook to the test suite.
