I'm having difficulty running the ping CRM with sail

I use sail, I use forward port db, but to no avail. What is missing to run the application?

./vendor/bin/sail up -d

or

FORWARD_DB_PORT=33061 ./vendor/bin/sail up -d

+++++++++++++++++++++ .env:

FORWARD_DB_PORT=33061

DB_CONNECTION=mariadb

DB_HOST=mariadb

DB_PORT=3306

DB_DATABASE=pingcrm

DB_USERNAME=sail

DB_PASSWORD=password

+++++++++++++++++++++

response:

Bind for 0.0.0.0:33061 failed: port is already allocated
