ANDAND condition should have an 'if true then false'

I am having problems compiling the following code:

@Composable
fun getWallethColors()= KotprefSettings.getNightMode().let {
    if ((it == MODE_NIGHT_FOLLOW_SYSTEM && isSystemInDarkTheme()) || it == MODE_NIGHT_YES)
        darkColors()
    else
        lightColors()
}

it throws this error:

Interestingly when I rewrite it as:

fun getWallethColors(isSystemDark: Boolean) = KotprefSettings.getNightMode().let {
    if ((it == MODE_NIGHT_FOLLOW_SYSTEM && isSystemDark) || it == MODE_NIGHT_YES)
        darkColors()
    else
        lightColors() 
}

@Composable
fun getWallethColors() = getWallethColors(isSystemInDarkTheme())

it compiles fine. I am new to jetpack compose - wondering if I am doing something wrong or if this is a bug.

This is a bug. Please file at https://issuetracker.google.com/issues/new?component=612128

If the compiler ever throws: e: org.jetbrains.kotlin.backend.common.BackendException: Backend Internal error, it is (by definition) always a compiler-level bug.
