Upgrading to Expo SDK 52 may lead to Babel errors, such as '.plugins is not a valid Plugin property', due to outdated configurations.
Issues with the babel.config.js file, including syntax errors or outdated Babel versions, are common culprits.
Steps to fix the problem include checking and updating babel.config.js, verifying Babel dependencies, clearing caches, and checking for duplicate packages.
Inspect other configuration files like postcss.config.js and metro.config.js, review Expo SDK 52 documentation, and seek help from the Expo community if needed.
