The flash drive is busy but there is no folder structure: how to return everything to its original form?

Question

Data recovery

Good afternoon!
After trying to merge files from the flash drive to the cloud (the operation was terminated by me due to the duration), the folder tree disappeared. I don't think this is a consequence. Attempt to restore files with Recuva: files were restored without a folder tree. I'm not sure it's complete.
The computer sees hidden files. On the command line, the DIR /x command displays "The volume on the device is unlabeled."
Folders in the STORE 1 and STORE 2 subfolders are visible, but their names contain invalid characters.
Also, the dates of change are strange: 2097, etc. Also, the size of the STORE 1 folder is more than 11 GB, although the flash drive is 8 GB.
This folder appeared apparently after I inserted the flash drive into the MAC. Accordingly, is it possible to extract something from these data?
What is the matter in general and how to return the files in a normal structure?
Any ideas and advice are welcome! Thank you.
