I am developing a React Native project. It was all fine until I decided to update Reanimated as the app would display error on android “If you want to use Reanimated 2 ….”. Since then, the app displays the following error on launch (pasting error from xcode):

Terminating app due to uncaught exception ‘RCTFatalException: Unsupported’, reason: ‘Unsupported’

Versions I am using :

    "react-native": "0.63.0",

It was working fine with react-native-reanimated 2.2.2 on ios, but now if I downgrade it back, it still wouldn’t launch.

I tried:

• versions 2.4.0, 2.8.0, 2.9.1, 2.10.0, 2.14.0, 2.17.0

• deleting the app from simulator and installing again

• clearing the cache

• deleting&installing node_modules

• deleting&installing Pods and Podfile.lock

Any help would be appreciated
