App crashing in simulator running on new M1 mac

I can run my app in a simulator on my 2019 mac without issue, but the same code will seemingly randomly crash when running on my new M1 machine. No error in the logs, I just see Lost connection to device. and the app crashes (but not the simulator itself). If I build from XCode I get a Thread 1: EXC_BAD_ACCESS in AppDelegate, but can't seem to track down the problem from there.
