@reduxjs/toolkit is not compatible with the official React 19 release #4759
Description
Hello,
I encountered an issue while attempting to use @reduxjs/toolkit with the newly released React 19. The installation fails due to peer dependency conflicts, as @reduxjs/toolkit currently specifies compatibility only with React versions ^16.9.0, ^17.0.0, or ^18.
Here is the error message:
