Native crashes on UE4 android game only in distribution build

As I build my game for development mode and install it directly from apk file to my device, it runs without errors and doesn’t crash, there are in-game ads and it is able to get variables from game-saves.

But once I build with Shipping and Distribution tags and upload it to Google Play I get errors on all devices that it is tested. (Installing directly through apk also crashes it.)

Here are backtraces-

Transfering to 4.19.2 solves the problem
