Unable to signin with my personal account

Hello,

I would like to connect my personal account and calendar to my main work account, but whenever I try to connect it I won’t find it in the accounts list. If I try to log in with that account a screen appears where it tells me that my account is migrating. Can you please delete my personal account so I can restart from scratch with it? The account is pacciani.edoardo@gmail.com, and I cannot manually delete it because I can’t log in with it.

If you need any additional information fell free to ask.

Thank you

Edoardo
