Update to Windows 10 ver. 1903 Deleted Valuable Folder

After installing this update everytime I tried to log into my user profile I was getting an error, after restarting this was fixed. However, many of my personal user settings had changed (default browser, background picture, windows bar colour ect).

All my applications were still on my desktop but none of my folders were showing. I found all the folders in the desktop folder, they just weren't displaying on the desktop for whatever reason. I dragged one folder from the desktop folder onto the physical desktop so I could use it. It all went well.

Upon returning to my PC today and turning it all, all my user settings have gone back to what they used to be and all my folders are now on my physical desktop. Except the one folder I moved is completely gone from my computer. I see all the files in my frequently accessed folder and file area on my windows file explorer but I can't access any because they're apparently all non-existent. My backups don't go back far enough for what I need.

Any help would be greatly appreciated.

EDIT: I think I was in a temporary user, moved my file to there and when I logged off it wiped it. Any ideas how to correct this?
