SFChart - Donut Chart - SelectionChangedListener crashing in newest version - Forms/Android

[Nick Barbato]

We just updated to version 15.1.0.41. Since this update our android build of the application crashes when selecting a section of a donut chart. The chart appears correctly, but crashes when a section is selected.

On selection of the donut chart section, we navigate to another page. This worked fine up until the update.

Any ideas?
