(node:6732) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originates
Either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_...ejections_mode). (rejection id: 1)
(node:6732) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

The error happens because your Node.js version on Windows 7 is too old to support the optional chaining operator ?. used in the Expo package. Update Node.js to at least version 14 or higher, then delete node_modules and run npm install again. This will fix the SyntaxError: Unexpected token '?' and the unhandled promise warnings.
