Resynced again and faced the same problem. Mainnet sync slows down somewhere near block 673700. Bitcoin ABC version v0.22.13-05d6cf915

Still extremely slow. Only around 800 blocks were synced for the past 6 days. Currently it's 1500 Blocks behind. It's syncing in 1TB NVMe SSD with lots of RAM and CPU. I'm ready to give more details if needed. Please help. Bitcoin ABC version v0.22.14-e6f40506a

It looks like everything is working fine, when looking at your screenshots. In your first message on February 19, your latest block is from the same date. In your second message on February 25, you are also up to date with a block from that date. There was an unusually long delay of 50 minutes between block 674781 and the following block, but that can happen due to natural variance in block intervals.
