That sounds really frustrating. I am assuming that you are using Blob storage, please let me know if that is not correct.
If you have enabled soft delete for your Blob storage, you can recover deleted files during the retention period. Soft delete maintains the deleted data in the system for a specified period of time, allowing you to restore the blob to its state at deletion. Please check if this is enabled for your storage account.
If you haven't enabled soft delete, unfortunately, there is no built-in way to recover deleted files.
