Steps to replicate the issue (include links if applicable):

• Go to https://www.wikidata.org/wiki/EntitySchema:E292
• Click the "check entities against this Schema" link
• Copy/paste the "SELECT DISTINCT ?work WHERE { ?work wdt:P31 wd:Q13442814 . } LIMIT 5" example query from the large light purple text field into the Query box below it
• Click the "run query to fetch entities (ctl-enter)" button
• Open the tab "Entities to check" next to the "Query" tab/box where you posted the SPARQL query

What happens?:

Below the big text field with the EntitySchema ShEx there is a panel with two tabs, "Query", and "Entities to check".
After clicking the run button this second tab should show a table with green and red column, with the first column the Wikidata item IRIs and in the second columdn the text "START" for each.

For example E174 this works fine:

But for E292 this stays empty (no rows):

What should have happened instead?:

I expect a table with example items for E292, just like for E174.

Other information (browser name/version, screenshots, etc.):

I wonder if this has to do with the Wikidata graph split and the split broke the EntitySchema stack?
