I emailed a link for you to download the newest backup. It contains your files from 2026-05-08 when the server was powered off, and two binary database files. The database files are .frm and .ibd. It should be possible to extract the data from them. I have googled it and found several different methods of recovering the data out of binary files like this. Let us know if you're able to extract your data and the method you used so we can provide this information to other people who have the same issue.
