hi

open the super administrator account as shown here

https://www.maketecheasier.com/activate-super-administrator-account-windows/

once logged into this account, create a new user account
try to transfer the data to this new account
Once everything is ok, delete the HS account, you can wait the time to be sure you have not forgotten anything

deactivate the super administrator once the new account is functional
