Description

This is currently blocking reanimated as it's preventing the autolinked modules from being loaded. The fix is sadly not correct because the OnLoad.cpp file is available ONLY on New Architecture and the <autolinking.h> is always generated.

i think this is blocking all autolinked modules on android
