I got a reproducible test failure on 5efa91f, which is part of a PR commit but which I don't think has changed anything that would cause this:

Fix SearchableSnapshotDirectoryTests.testDirectoryReader (#51343)
b88a798 
This commit fixes the SearchableSnapshotDirectoryTests.testDirectoryReader 
which fails on empty/fully deleted segments. The test now iterates on all 
LeafReader to verify that they have the same number of docs. It also check 
all fields within the segment.

Closes #51326
