### Bug Report

Flex crashing due to `Thread 1: EXC_BAD_ACCESS (code=1, address=0x3006d756c6f5628)` in FlexNetworkObserver.

` unsigned int methodCount = 0;
Method *methods = class_copyMethodList(class, &methodCount);

It crashed at class_copyMethodList

Only crashing when fles is added via SPM (Package.swift), works fine if flex is added via cocoapod
