Sorry for the delay. I got a working example here:
I poked into it a little bit and it seems to be connected to
Steps to reproduce:
- Navigate from Second Fragment to Child nav graph (with non-nullable parameters).
- Navigate to Third fragment using SafeArgs and the app crashes.

Note: If in step 2 SaveArgs is not used then navigation works correctly. More information is here:

Ups a typo: Navigate from Second First Fragment to Child nav graph (with non-nullable parameters).
Note: sorry for the spam but I am not able to edit my own comment.

This has been fixed and will be available in navigation 2.6.0-alpha08

Fix missing non-nullable arg when rebuilding hierarchy
When navigating with NavDirections, args is populated with an empty bundle. This causes issue when we rebuild parent hierarchy while adding a new entry to NavBackStack. If the Entry being rebuilt contains a non-nullalbe arg, i.e. Long, this empty bundle will cause an exception.
Test: ./gradlew navigation:navigation-runtime:cC

The following release(s) address this bug.It is possible this bug has only been partially addressed:
androidx.navigation:navigation-runtime:2.6.0-alpha08
Description
Version used: 2.2.0
Devices/Android versions reproduced on:
* Samsung Galaxy Note 10+, Android 9.0
* Google Pixel 4 XL, Android 10
After updating the navigation plugin to 2.2.0, I'm encountering a crash as a result of XML inflation errors from navigation graphs with deeplink schemas. Looking a bit deeper, it seems like this is being caused by a NullPointerException via java.util.regex.Matcher.reset, invoked from androidx.navigation.NavDeepLink.
This is the deep link format that is causing this issue:
<deepLink
android:id="@+id/confirmation_deep_link"
app:uri="envoy://sign-in?{data}" />
This crash does not occur when navigation 2.1.0 is used.
