It won’t let me delete my comment, just says “error 400.”

Every time I try to delete my comment on House of Dragon it just say “error 400” in yellow. It actually won’t let me do anything, it won’t let me edit, delete, anything. I want to delete it but it just says “error 400.” It won’t let me do anything on the app on my iPhone or iPad or the website. I don’t have a reference number because it posted it on January 23,2023. I had this same problem a few months ago with the The Last of Us and posted here and you guys ended up fixing it. You had trouble finding it but eventually did and fixed it. Please help with this too. I’ll post a picture of the error and a picture of my comment.
