1: Either you must allow less secure apps or use app password by enabling 2 step verification on your gmail acc.

2: Disable any antivirus on your machine(this is something no one will tell u but is necessary in many cases).

3: Don't forget to clear your cache (sometimes it don't take updated content from .env file)

4: You don't need to change anything in Mailer inside config directory(not recommended), you should use env variables
