Which op amp, and where did you get yours?
200 µs seems too slow even for fake TL074s but I dunno, could be at least part of the problem if they came from AliExpress or eBay or the like.
To be clear, your AC coupling is before the comparator, right? And nothing after the comparator but a voltage divider and an op amp buffer? No capacitors in any of that?
Added: Scope pictures from an article linked in the above topic:
The genuine TL074 comparator is turning on in about 2 µs. The fake is much slower — but it’s a whole lot faster than 200 µs.
