Having a crash on start up, Android

This error just started popping up when I build to android, The game launches but crashes after the launch image. I’m sure I didn’t change any blueprints for the start up so this is pretty confusing. I’ve tried it in both shipping and development builds and got the same crash.

It’s talking about CPP but I’m using blueprints so I don’t really understand how I can track down the issue. Any suggestions would be great. Thanks!

Oh, and it doesn’t crash when testing on the PC. Only when on mobile
