The problem is from Gutenberg and there's an opened issue on it.
WordPress/gutenberg#43053

In my test, I deactivated all plugins on my testing site including Authors when no positive result in my testing and after that, i create a new simple plugin with a new shortcode to get post ID in loop and realised it’s showing same post ID for all the posts which shows this is not Authors issue but probably the shortcode is not been executed inside the block loop or the block is not resetting queries.

The proposed workaround cannot work for us because we're not rendering the shortcode. I think we'll be on the lookout till this is fixed
