Is it a problem of use, or a problem of Navigation?

[lutobler]

I have the same problem. For me this occurs when navigating between two components using the bottom bar, and both components use their route's BackStackEntry as a ViewModelStoreOwner. It occurs for me when tapping back and forth between the views quite fast, so when the transition animation is still running.

[trevjonez]

Seem that the likely root cause is with the integration between the androidx navigation and lifecycle libraries.

[josh-Muleshi]

can you change the NavController to NavHostController ?

This issue is stale because it has been open 30 days with no activity. Remove stale label or comment or this will be closed in 5 days.

[svenjacobs]

I got the same crash in Crashlytics from a customer but cannot reproduce it. Is there a fix for this?

[TheNephilim88]

Same here, but still cant reproduce on my own :(

[James-Aidoo]

Same here. Reproducing it is the problem. Seems impossible

[Minoro75]

after setting animation duration scale in Developer Options of device - crash reproduces every time.
