Component used: Navigation Version used: 2.5.0-alpha04 Devices/Android versions reproduced on: Samsung GS20 / Android 12

In Navigation 2.5.0-alpha04 a change was introduced, that causes my app to crash immediately at start with the following message:

My app features a splash-screen using the new Splash-Screen API. Everything worked as it should before.
