Hi, I’ve try to recover whAtsapp in my old phone (my new one broke) and for some reason it keeps say “couldn’t restore chat history”

1- my phone storage in empty

2- the phone software is updated

3- I cloud has more than 150 gb free space,

4- iCloud is the storage model that I choose for whatsapp

please help nothing works and I need the WhatsApp app ASAP.
