Hello,
This may mean that the current account is corrupted. Run the command prompt as an administrator and execute the following two commands to create a new local administrator account:
net user User ****** /add (User is the name of the newly created account, ****** is the password of the account, you can adjust this command yourself)
net localgroup administrators User /add (To grant administrator rights to this account, change User to the account name created in the previous command)
If there are no problems under the account, it means that the profile of the old account is corrupted and cannot be repaired, but you can migrate the profile of the old account to the new account according to the method of "Copying files to the new user profile" in the following link, and then you can use the new account.
