 **Bugfixes:**
 
 - Fixed an issue where files outside the Cypress project directory were not calculating the bundle output path correctly for the `file:preprocessor`. Addresses [#8599](https://github.com/cypress-io/cypress/issues/8599).
+- Fixed an issue where Cypress would not run if Node.js version `22.7.0` was being used with TypeScript and ES Modules. Fixes [#30084](https://github.com/cypress-io/cypress/issues/30084).
 - Correctly determines current browser family when choosing between `unload` and `pagehide` options in App Runner. Fixes [#29880](https://github.com/cypress-io/cypress/issues/29880).
