App crashes - cannot figure out crash report

Hey, our Capacitor app crashes on various iOS devices. The error only says "EXC_BREAKPOINT (5) Application temrinated". I have the crash log, but I don't where to start looking as I am not an iOS engineer.

I would really appreciate any kind of guidance! Thank you!

( I have attached the whole crash log as a text file )

Are you able to duplicate the crash on a device? If so, you could then run the App while connected to Xcode and hopefully see where the problem(s) are. What is the name of the App on the App Store?
