Kotlin Multiplatform project building keeps failing after adding dependencies

Question

I created a Kotlin Multiplatform project (for the web).
After adding a dependency (in my case io.ktor:ktor-serialization-kotlinx-json:2.1.1) the building of the project fails. I get following exception:

e: java.lang.IllegalArgumentException: Sequence has more than one element.

My build.gradle.kts:

plugins {
    kotlin("multiplatform")
    id("org.jetbrains.compose")
}

repositories {
    google()
    mavenCentral()
    maven("https://maven.pkg.jetbrains.space/public/p/compose/dev")

kotlin {

                }
            }
        }
        binaries.executable()
    }
    sourceSets {
        val jsMain by getting {
            dependencies {

        val jsTest by getting {

This is a bug in 1.6.10 — https://youtrack.jetbrains.com/issue/KT-52047. Workaround is to use 1.7.10 and 1.2.0-beta02 Compose.
