Did you set up with a business account from out of box? Is this Windows 11 Pro? Did you choose the "set up for work or school" and then log into your business email address that way?
This bit of the info is important, as if it is, your computer is Entra domain joined, and you don't have local admin right. Admin right is from the domain/network admin user in the business tenant. Not the end of the world, but just needs to use a different method around it. Let me know if you can confirm this first.
