I have what seems to be a sync issue on 2.4.1 full node fwiw, also using Win64. My symptom is that syncing appears to freeze on July 13. After some hours stuck on the same clock time, I'll stop and restart it to find that the sync clock has advanced by a couple of hours at restart but goes no farther until another restart - rinse, repeat.
Are you using a HDD or a SSD for your data files?
If HDD then it may be too slow. I found that until recently my HDD worked fine but with some of the most recent changes it was no longer fast enough to keep up so I switched over to my SSD and it started making good progress on catching up until this exception happened.
Waiting on 2.4.2 so I can get going again...
