If you have an active Microsoft 365 Personal, Family or Premium subscription, you can reinstall it from your associated account at https://account.microsoft.com/services . Uninstall any older software versions first.

If you prefer to use Office 2021, make sure that you can access that product, that is, make sure that you see it in a Microsoft account. You should also cancel your Microsoft 365 subscription (see https://support.microsoft.com/en-us/accounts-billing/subscriptions/cancel-a-microsoft-365-subscription). There is no need to pay for the subscription if you are not using it. You can always resubscribe later, if you change your mind.
