You have a library that depends on React 18, or rather, is not compatible with React 19.

In your case, I am not sure which library that might be though. Maybe, if possible, share your package.json dependencies.

[yashaswi1004]

what if i am using the components from my own package and that package is using react 18?

[icyJoseph]

Right, I think you need to upgrade to 19, IIRC.

Thank you!
