I just received my new iPhone 13 Pro and I’m trying to sync all my apps via iCloud.

"I’m having trouble getting all my apps restored to my new phone via iCloud. It seems to have stalled so that I can’t open some apps like Apple Books. What should I do to finish setting up my new phone?"

Troubleshooting a Frozen iPhone:

Start with Unfreezing it. Once unfrozen, download it one item at a time, rather than in batches as such.

• If the Screen isn’t Working on your iPhone or iPad - Apple Support



• If your iPhone is Stuck on the Apple Logo - Apple Support

• If your iPhone Won't Turn On or is Frozen - Apple Support

• If you Need More Help - iPhone - Apple Support

"Whom to Contact:

I’d say contact the Developers of WhatsApp and find out how to get around this. Their software seems to be getting the way here. Visit the site in the App Store, and your find their Contact Us info."

i´d call apple, the problem is the icloud ios backup restore...

The solution is here:
