I'm trying to set up the startDestination page based on whether the room database has the specified value, but it keeps getting this error

You could do a calculation in splash screen if possible.

First of all, this isn't how you should be handling login in Navigation, this is something we've covered a couple of times: https://kotlinlang.slack.com/archives/CJLTWPH7S/p1630878904292300?thread_ts=1630873265.287300&cid=CJLTWPH7S

Secondly, this isn't how you pass arguments to your start destination: the start destination string needs to match the route string exactly, character by character. You'd use the defaultValue on your argument: https://github.com/google/accompanist/issues/897

But again, you shouldn't need to do that at all

Passing your userId as an argument is generally going to lead you to source of truth issues - Room is your source of truth so your Home screen should be your start destination and collectAsState() on your Room DB to get the current user, conditionally redirecting the user to login if the current userId is null
