How to go about filing a bug? I think I've found one in the androidx.compose.material3.adaptive.navigation.

It's a crash when switching tabs from a screen with a ListDetailPaneScaffold

java.lang.IllegalArgumentException: item can't be saved

I could be wrong, but from what I've seen a lot of the Compose related issues are submitted to the Google Issues Tracker: https://issuetracker.google.com/issues?q=status:open%20componentid:610478&s=created_time:desc

You need to be signed into a GMail account to submit.

Thanks for the link! I had forgotten the issue tracker exist altogether and looks like the same issue is already reported (https://issuetracker.google.com/issues/377330009).. and unsurprisingly it's a user error!
