Process definition Email issue after instance upgrade to 13.0.0 version

Dear All,

After instance upgrade, we have observed that In process definition -> Send Message Events if we add any Team(With explicit and implicit members) then Email is sent to all members of Team.

Steps to reproduce:
Create Team with explicit and implicit members say XYZ Team
Create sample process definition on Accounts module which send Send Message Events on record creation/update.
Add Send Message Events and in CC receipt add XYZ Team and save

Now create new Account and check if Email sent to only explicit members of Team or sent to ALL members in Team.
Please suggest quick fix or alternative to issue.

Kindest Regards,
