Hello, thank you for reaching out to Microsoft Q&A.
Hi, Parent or guardian consent is required for creating a Child account. Based on the description provided, it seems that you're having trouble creating a Child account.
Are you experiencing the same error when trying to provide consent to a Child account using both options?
You can choose 'I am not a parent or guardian', then choose to email them for help. Then enter your email address, and once you provide consent, the child's account will be ready.
If you're having issues, open an incognito tab and try creating a new Microsoft account from https://outlook.live.com/ (Select create free account) and see if it helps.
Let me know how it goes.
