@Deniz Mehmet - There is a locked shape over everything:

I can’t see the shape that you shared on my screen. How can I unlock the article? (As I can’t see your locked emoji, I have to solve this another way.

@Deniz Mehmet - If you do not see this Long press to unlock text, then you are either not the board owner or at lease are not signed in as the user who owns the board:

Because this board is in a Free Plan, any registered account user can duplicate this board by clicking on the board title and then using the Duplicate action, which is what I did and how I was able to unlock the shape (once you duplicate a board, a copy is made in your Miro account/team and you are the owner of the copy.

**WARNING** The board is large and will take a while to duplicate.

Thanks.

 I fixed the problem. Have a great day.
