Instagram loading issues hidden messages

Instagram highlights of someone is visible on their account but not loading, And this is happening just with a particular person when I try to view it. The highlights section is visible on their account when I open it which means they haven't hidden their stories from me, because had they blocked me from viewing stories, I wouldn't even have been able to see the highlights section on their account. What could be the reason for the same?

Hello there, Has anyone have same problem with me? Before this I kinda blocked my friend from instagram (and we have some collaboration posts), but when I unblocked him, and we following each other again, the collaborator post are missing from my profile but still exist in my friend's page. Is there anyway to recover those collaborator post to appear on my feed again? Thank you.
