Hi @camoreo!
Maybe you have the Classic Editor plugin installed? https://wordpress.org/plugins/classic-editor/
Which plugins do you have active?
Doesn’t matter whether it is installed or not. I was using the block editor and one day, after an update, it disappeared. I tried uninstalling the classic editor plugin. I still don’t have the blocks.
Which other plugins do you have installed?
Do you see the block editor for new posts?
When I click new post, I have the option of editor or Divi Builder. The Block editor does not appear above the right column either. Block just totally vanished.
