iOS app crashing when running with Appium

My app always crashes after specific steps when using Appium (both automation or manual with Appium inspector open), but works well when Appium is not running. My app crashes even when I don't use the inspector (just leaving it open).

I tried with both real device (iOS 10.3.3, iOS 12.4, iOS 12.2) and simulator (iOS 8.4, 10.3, 11.4, 12.4), on multiple Appium versions (1.6.0, 1.13.0, 1.14.0) but the result is still the same. Appium also does not leave any log on crash. I only have the iphone crash log here:
