Standing water in a crawl space with a functioning sump pump suggests:

A working pump and standing water is a contradiction worth resolving rather than dismissing, and there are only a few ways both can be true. Water may be arriving faster than the pump's rate — high water table, a storm event, or a discharge that recirculates back into the crawl. The pit may be positioned or set too high relative to the crawl's low points, so water pools where the drainage does not lead to the pit. The perimeter drainage feeding the pit may be blocked or absent, so water in the crawl never reaches the pump at all. Or the discharge may be obstructed downstream, so the pump runs and moves nothing. The inspector reports the standing water as a condition, notes that the pump operated, and identifies that the system as a whole is not managing the water — which is the finding, regardless of which of those explains it.

Water can stand despite a working pump if inflow exceeds the removal rate or if the water never reaches the pit — a misplaced or high-set pit, blocked perimeter drainage or an obstructed discharge all produce that. The system, not the pump, is failing.

Crawl space drainage relies on grading or perimeter drains routing water to a pit positioned at a low point, with a pump sized to the expected inflow and a discharge that carries water well away. Standing water indicates a failure somewhere in that chain.

Working Pump, Wet Floor, Broken System. The pump is one link. Ask whether the water can reach it and whether what it pumps ever leaves.

Check where the discharge terminates. A short discharge recirculating back into the crawl produces exactly this picture with a perfectly good pump.
