Is it a personal email address (for example, email@example.com .com) or an email address offered by your organization (if using a domain by Microsoft it would look like firstname.lastname@example.org)?
Can you login Teams on the web with this email address successfully? Or it would return the same error: AADSTS90002: Tenant not found.
If Teams on the web is working without issues, please exit Teams and clear the cache of Teams.
And retry to see if you are able to login with your account.
