[HELP] iCloud Drive “deleted” my Cubase projects - found them in a hidden trash I can’t open!

So my .cpr Cubase project files suddenly vanished. After a full-disk search I discovered they were sitting in a hidden iCloud Drive trash folder:

/System/Volumes/Data/Users/<me>/Library/Mobile Documents/.Trash/

I can list them in Terminal (ls shows them!), but Finder refuses to open that folder.

Under - /Users/<me>/Library there is no Mobile Documents app.

Using GO to get to ~/Library/Mobile redirects me to iCloud Drive folder and I can not find the mobile/documents folder. under the Documents folder in the iCloud Drive I see no trash nor .trash folder.

fcopyfile failed: Stale NFS file handle.

What’s actually happening

• My iCloud storage got full (5 GB/5 GB) a lot of time ago.
• As far as I understand when that happens, iCloud quietly moves or “unlinks” local files and dumps them in .Trash under ~/Library/Mobile Documents/ - without showing it anywhere in Finder.
• Apps that constantly rewrite files (like DAWs) trigger this more often because iCloud sees each save as a delete/re-upload.

🧰 What I’ve tried so far

1. Found the real data using terminal with:

sudo find / -type f -name "*.cpr" 2>/dev/null

2. Verfiied it exists with

ls -la ~/Library/Mobile\ Documents/.Trash

1. Tried to copy them out - Finder and cp fail with stale-handle errors.

How do I safely extract every file from iCloud Drive (including that hidden .Trash) onto my Mac’s internal drive?

PLEASE ADVISE!!! thank you love you bye
