macos – Apple Books in Mojave pasted

I launched Apple Books on my MacBook Pro 2016 (10.14.5) to continue reading a book I had started on my iPad Pro (where I bought it).
As expected, the book was in the cloud, so I double clicked on its cover to download it. He requested my Appleid and my password, as expected and then … he began to download another 16 titles before this, which completely freezes the application.
The download is not progressing, nor can I stop it. Restarting the application, or even after a reboot, gives me a library full of gray elements without any possibility of forcing a download …

What can I do to get it off?
I even went into Preferences and downloaded automatic downloads of purchases.
