Can lost iCloud video files be recovered if they disappeared without warning?

For the past few years I’ve been gathering dozens of videos for inspiration (ranging from 5 to 30 seconds long). Back in May 2025 I had uploaded these 100+ files from Google Drive to the iCloud Files app on IOS (organizing them in various folders).

But sometime between August and September, when checking for the files all of them were missing except for 10 without any warning. This was less than 30 days since I last checked, so I went to my recently deleted but none of them were there. The folders they were kept in still existed, just now empty. We had plenty of storage left in the family plan (mine being 1/5 of everyone else’s so I don’t know why my files were attacked).

This happened two weeks ago now and I’ve lost so much motivation to do anything since my files ca just magically disappear. Can somebody help me?
