The Economist had an article a few months ago talking about how modern satellite fleets were so bright, they were threatening to make earth based astronomy impossible. Its title: "Goodbye, darkness, my old friend".
They probably threaten some space telescopes, too. The Starlink satellites are a little higher than Hubble. I would imagine they might take up a decent amount of field of view to Hubble, by being closer.
They are at almost the same altitude, 540 km vs 550 km. There is probably almost never a starlink sat in view for the Hubble, they would need top be right on to of each other, the satellite would pass by at a very high speed and you wouldn't see another for days.
