The issue with nostr:nprofile1qqs24yz8xftq8kkdf7q5yzf4v7tn2ek78v0zp2y427mj3sa7f34ggjcpzamhxue69uhhv6t5daezumn0wd68yvfwvdhk6tcppemhxue69uhkummn9ekx7mp0qyg8wumn8ghj7mn0wd68ytnddakj703s8dt not loading any image and video is resolved now.

Apparently, the issue was my fault. Wittingly and unwittingly I added hundreds of relays. These somehow caused #Amethyst issue with loading image and video.

I removed all the relays and set the relays to Amethyst's default ones. That solved this issue.

Lesson learned.
