Mess after new editor

Hi all,

after I have updated wordpress and now using the new editor (or lets say i try) I am not able to make this gonna work. As soon as I edit a page, the editor opens with a small popup saying “Welcome to the wonderful world of blocks!”…. that’s it!! I can’t close this popup and cant use any other option on the page to edit the post, whatever I click, there is no response.

Can anyone help?

Thank you
