I want to start by saying thank you for this awesome project. We are using a custom PTE model, which may be the entire issue here. This crash only happens on an Android Emulator (I'm using a M4 Mac), it works properly on real devices and on the iOS simulator.

Description
Hi all!
I want to start by saying thank you for this awesome project. We are using a custom PTE model, which may be the entire issue here. This crash only happens on an Android Emulator (I'm using a M4 Mac), it works properly on real devices and on the iOS simulator.
