Example project attached with repro. To cause crash add enough items to enable scrolling then scroll the list.

Code that causes crash is:

        LazyColumnFor(
            items = items,
            modifier = Modifier.weight(1f),
            contentPadding = InnerPadding(top = 8.dp)
        ) { todo ->
            Box(
                // TODO: This causes LazyColumnFor to crash so disabling for now
                Modifier.animateContentSize()
            ) {
                if (currentlyEditing?.id == todo.id) {
                    TodoItemInlineEditor(
                        item = currentlyEditing,
                        onEditItemChange = onEditItemChange,
                        onEditDone = onEditDone,
                        onRemoveItem = { onRemoveItem(todo) }
                    )
                } else {
                    TodoRow(
                        todo,
                        { onStartEdit(it) },
                        Modifier.fillParentMaxWidth()
                    )
                }
            }
        }
