I'm getting the following after upgrading from kotlin 1.5.31 to 1.6.0... did anyone ever encounter something similar and can help me out here?

I'm seeing this right now. Have you had any luck resolving it?

Are you using Jetpack Compose? This is the stacktrace I have:

java.lang.IllegalStateException: Symbol for kotlin.collections/mutableMapOf|-4813910536206556932[0] is unbound

I fixed it by simplifying some code that looked like this:

val x = mutableMapOf("something" to "something").apply {
    if (bool) {
        put("another", "thing")
    }
}

To this:

val x = mutableMapOf()
x["something"] = "something"
if (bool) {
    x["another"] = "thing"
}

If I were you I'd check all your uses of mutableMapOf, particularly in places that are nested deeply (this particular case was inside a function inside a when block).

Thanks, I will have a look!

It happened again for me. The one thing that was consistent was that they were both inside of a withContext(<http://Dispatchers.IO|Dispatchers.IO>) block.
