Problems

1.Could not initialize class.org.kotlin.jetbrains.KotlinSourcekt

🔥

when react-native init project_name is not working then we can run the command for a specific version

🔥

That is error is from the new version 0.69.0 You can use npx react-native init ProjectName --version 0.68.2 and then upgrade to v 0.69 later.

go to the gradle scripts and change these setting

it will at least form the original native kotlin structure in the project structure

🔥

One more thing ⇒ always check the gradle version and parellely the supported kotlin version for that gradle

as in the above image my android studio has kotlin version 1.7.20 and gradle plugin version 7.4.0

so it can be a problem

sol2

One more thing I have done that, I have changed the directory and then created the project via


npx react-native init project_name

after that I have opened it in my android studio

and then it worked
