In Intent, it doesn’t recognize .java after ::class

    The solution is:

    In build.gradle (:app) file, in dependencies, you should change appcompat version to 1.4.2.

    befor error:

    dependencies {
    implementation 'androidx.appcompat:appcompat:1.5.0'
    ...
}

    And when I changed the version to 1.4.2, the problem was solved

    dependencies {
    implementation 'androidx.appcompat:appcompat:1.4.2'
    ...
}

    And make sure the kotlin version is 1.5.0

    Kinda strange because it seems good to me. Try this.

    Remove the lateinit and declare it directly when you need it, maybe it will solve the problem. 

    val intent = Intent(this, LauncherActivity::class.java)

    I don’t think the this@KotlinActivity is needed in this case.
    Let me know if this fix it

    UPDATE

    Are you sure the findViewById<TextView>... is correct ? Shouldn’t it has a declaration before ? Like 

    val view = findViewById<>...
