You said you "purchased the Microsoft Business subscription and complete the registration" yourself, it's a strong indicator to assume that you are an administrator. However, since you didn't clearly mention whether you are a sole administrator or not, please follow the appropriate scenario below to move forward:
If you are not the only admin Please check to see if there are other IT admins in your company who can help you with the reset MFA for your account and share with them the steps outlined in the article Manage user authentication methods for Microsoft Entra multifactor authentication. This process usually only takes a couple of minutes.
Once finished, the next time you sign in, you will be prompted to set up Microsoft Authenticator again from the beginning, and verification codes should be delivered normally. If appropriate, you may also add an additional authentication method, such as SMS or email, to help ensure continued access in the future.
If you are only admin
Why this helps: The sequence separates identity, permission, and local-client issues before broader reinstall work.
If it still fails: Save the exact error text, account email, and screenshots for Microsoft Support.
Keep Local Files Moving in WPS During Gen Account

WPS Office cannot fix Microsoft account sign-in, Authenticator, billing, activation entitlement, OneDrive ownership, or admin locks. Those stay on the Microsoft side.
While that recovery continues, WPS Office can keep local editing moving:
Download and install WPS Office.
Open Word, Excel, PowerPoint, or PDF files in the matching WPS app.
Save a local working copy until Microsoft access returns.
Move or sync files back through your normal workflow afterward.
If you need a practical local workspace in the meantime, try WPS Office.
Habits That Reduce Repeat Gen Account
Keep a backup verification method on important Microsoft accounts.
Record which account owns each purchase, mailbox, and device license.
Sign out of unused Microsoft profiles on shared PCs and update Office regularly.
Back up critical files before repair, reset, or reinstall actions.
