Hi, there I'm having trouble developing my developer store

https://jiwoo-dev.myshopify.com/ I created a developer store.

However, there is a problem in managing themes using the shopify CLI.
CLI commands do not work. Commands like ‘shopify theme pull’ and ‘shopify theme serve’ are rejected. This issue only occurs when creating a developer store. I need help.
thank you.

The error code is attached.
