We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

You won't get much empathy or help here. If you don't have a backup, then consider it a lesson learned. We do feel your pain, but it's also one to remember so you have backups the next time this happens.
While Microsoft is guilty of a lot of things, these kinds of issues typically end up being a PEBKAC error.
If you really want the data back, send it to a professional.
Otherwise check out the program called "Test Disk": https://www.cgsecurity.org/wiki/TestDisk
It may help find your lost folder.
