If you include Android apps in the category of "new projects," then new projects using Java and Kotlin are being launched all the time, including by companies that were not previously using Java.
OP did ask for Kotlin, so I guess it counts. Because I don't think people really start any new code using Java itself. Kotlin is the officially supported language. And there's just significant tangible benefits of using Kotlin over Java (e.g. Compose).
