iPhone 11 Pro iMessage won't scroll past December

iMessage keeps loading

So I have been trying to scroll back in my messages in an imessage chat and I can't go further back then December for some reason, it just keeps on loading but nothing happens. I have tried to restart my iphone 11 pro a few times and even tried to make more space in the storage. I've tried to load the messages with wifi on and with mobile surf but it does not seem to work anyways. Does anyone has an answer or possible solution to issues like this?

Could it also be that my iphone has the iOS 18.6.2 version?
