Sample project attached
- Application with Navigation Page style navigation
- Child page contains a ListView, with Context Actions attached to cells
Reproduction steps for Sample project:
1) Tap "Tap me" on the Main Page to open child page
2) Swipe to open Context Actions for any cell, do not close Context Actions
3) Execute Back navigation:
- Use either standard "Back" button of Navigation Page, or
- Swipe from Left to Right starting from the edge of the screen (Back navigation with swipe)
4) Reopen Child Page
5) Try to open Context Actions again.
Context Actions could not be opened, until app is killed and restarted.
Context Actions should continue to work.
- iPhone 5C, os 10.3.2 / 10.3.3
- iPad, os 9.3.5
This appears fixed as of 2.4.0pre1.
I've reviewed the issue against 22.214.171.1249-pre2.
Now, instead of simply "context menu not opening" behavior, application crashes.
I cannot reproduce this crash. The context menu opens and closes after the initial back navigation as expected. Please validate that you have completely cleaned your solution (including bin/obj folders and deleting the app off of your device or emulator) and that your package versions are aligned.

I've updated the sample project (just in case).
Also made sure one more time that bin/obj (and packages) are cleaned up.
Here is an adjustment original steps to reproduce the crash mentioned in step 2.
After step 4, Reopening Child page (with the list). I immediately attempt opening the context menu on the list. Then the crash happens.
If I attempt to tap the list, or e.g. select any cell - crash won't happen and the context menu opens.
Okay -- I was able to get this to crash on an iPhone 7 with iOS 11, but it should be noted that this is device-only. Emulators do not crash, which is a critical point to note. This will need to be looked into further.
