Hello, thank you for reaching out to Microsoft Q&A.
If you see your Office Home 2024 license under your Microsoft account here https://account.microsoft.com/services, but you are still asked to buy an Office 365 subscription when launching Office applications, you can use the Office License Removal Tool to remove all previous Office licenses and then reactivate your product.
You can download and run the Office License Removal Tool from the official Microsoft website here.
