Answer 1

1) Don't use the "composer update" command to install a new package, use composer require guzzlehttp/guzzle
2) Check that there is a guzzlehhtp folder in the vendor folder
3) The following configuration should be in the .env file:

MAIL_DRIVER=mailgun
MAIL_HOST=mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null
MAILGUN_DOMAIN=sandboxXXXXXX.mailgun.org
MAILGUN_SECRET=key-XXX
