Has anyone encountered an issue with an iOS app that includes kotlin multiplatform code crashes on start on iPhone 5c when downloaded from app store? Local build works fine, ipa from app store seems to have this issue.

crash stacktrace?

I am unable to get the stacktrace as it is happening in release version that is download from app store. Since it crashes on startup, crashlytics doesn’t report anything either.

You can still look in xcode to see if the automatic crash reports exist from the app store. Should work regardless of crashlytics.
