Shortly: The required symbol androidx.compose.runtime/LaunchedEffect|-576771147392862334[0] is missing in the module or module dependencies. This could happen if the required dependency is missing in the project. Or if there is a dependency that has a different version (without the required symbol) in the project than the version (with the required symbol) that the module was initially compiled with.

iOS build fails with this message. any help?

This looks similar to https://github.com/JetBrains/compose-multiplatform/issues/2046

I actually mentioned this in my blog post 🤦‍♂️
