That helps not even an iota. WE DO have a problem. Our games are completely gone, or I imagine they are somehow still in our PCs, but we don't know how to access them.

It does tells something. He must be doing something you guys have not.

Anyway this might help

8. World save issues - Character/world gone.
Valheim saves both character and worlds in separate folders in:
C:\Users\ <username> \AppData\LocalLow\IronGate\Valheim
Sometimes a save-file gets corrupted. Go to your above mentioned directory. Your world will have files named with .old rename the files and remove the .old extensions and answer YES, when it prompts you if you want to overwrite a current file with the same name.
One easy solution to try is simply to stop Steam Cloud Sync.
If you have some program or anti-virus that prevents files from being created and/or edited on C: you will prevent any kind of character/world files from being created or any progress saved on them.
If you share computer (with different logins) with a family member, but you both share Steam account. You can have issues with Steam and Cloud Saves. Example:
Player 1 logins on computer, starts Steam. (then Steam Cloud saves will sync files on launch) then when you exit the game, Steam Cloud saves will sync again) if then player 2 launches the game from the shared Steam account, player 2’s local files will be prompted by Steam if player 2 wants to overwrite the files on C: - This can lead to issues if players 1 and 2 don’t always have Steam connected and sync every time correctly. (like quickly close the computer for example so Steam doesn’t get the time it needs to sync correctly)
If you are having sync issues or can't find your local savefiles, download your Cloud Saves here: https://store.steampowered.com/account/remotestorage
On a dedicated server, if you don’t close the client correctly, you can get corrupted files.
