Tokens are not getting Clear in CC field in EASY EMAIL MODULE

In my Drupal 10 setup, I’m using ECA to send an email upon user registration. The registration form includes a CC field. In Easy Email templates, there’s a “CC” field where I can specify either a static or a token-based value. I used the token for the user’s CC field from their profile.

When the CC field is empty, I get an RFC 2822 compliance error:
> Error sending email: Email "[user:field_cc_email]" does not comply with addr-spec of RFC 2822.

However, if the CC field has a valid email, everything works fine. How can I fix this?

I tried token filter module i enabled it, in text formats i had tickmark the settings as well still am facing same issue
