Delete google admin console account

Hello FL,

I need your assistance to delete a google admin account.

I am following Googles instructions given here:

I am unable to delete my account as this message shows:

I have followed Googles instructions for closing all projects, my issue is detailed here:

I need you to find the blocking issue and close the account. I will provide you with the required access for Google admin console and Google cloud project. Pleast start your proposal with GCP.

Thanks.
