Hello there,
You might be logged into a different account hence you cannot see the files on this account.
If you try to sign in to Windows and receive the error message, "We can't sign in to your account", or you see an action center notification saying “You’ve been signed in with a temporary profile,” Windows will create a temporary profile and sign you in to that one.
Here are some things to try to get signed back in to your Windows profile: https://support.microsoft.com/en-us/windows/windows-error-message-we-can-t-sign-in-to-your-account-18d55f00-a6e7-9106-29ee-54fa223c0ca8
Hope this resolves your Query !!
