Same here. Upgrading from React 16 to React 19, I am getting

React is not defined
ReferenceError: React is not defined

Everywhere where React was not imported. This should not be the case with React 19 anymore. I guess the issue is during the migration to React 19 from React 16 and it is somehow internal.

Any help very much appreciated!
