90% of my files on iCloud "Zero Bytes" size

On Thursday 25 I bought an iPhone XS and transferred my data from the old iphone with the new iphone migration assistant without depending on the cloud (both iphone with last iOS 13 public release). On Friday morning, the new iphone automatically synchronized with my icloud account and 90% of my files on my icloud appear "Zero bytes" of size. I need to recover my files approximately 25GB of data and all the work of my life! URGENT!

Same thing happened to me. On my Mac, iPhone, iPad and website everything is inaccessible. I did submit a report and am hoping they're looking at it.

Same thing here.
I recently wanted to re-edit an important video project I didn't touch for the past 6 months, and it's now zero bytes!
This made me sniff around my iCould files and to my surprise lots of them suffer the same illness!!

That's totally unreliable!!
Can anyone at Apple check this? Otherwise, what's the point in iCloud files if they can vanish without notice??
