Hello,

We have this crash on Android that uses MapBox SDK. The crash seems to be happening for one of the clients that is located in Chile. They are browsing the maps around Chile region. None of our code seems to be involved. Do you have any idea what may be causing it?

Environment

• Android OS version: Android 10, 11
• Devices affected: all the android phones we tried
• Maps SDK Version: com.mapbox.mapboxsdk:mapbox-android-sdk:9.6.2
