Severe Performance Degradation On Upgrading To RN 0.74

[udasi-jew-peter]

Old Version

0.72.8

New Version

0.74.3

Description

We are noticing a massive performance degradation after upgrading to React Native 0.74.3. We were intending to try and enable the new architecture to help improve our app's performance but after upgrading React Native without the new architecture enabled, we are facing a performance issue. It is very obvious since navigation transitions seem to stutter, button interactions as well as lotties are janky. Even input field feels unresponsive for a few hundred milliseconds after entering 1 character.

Steps to reproduce

I am not sure what steps to reproduce I can share, since I couldn't find any other issue mentioning this problem. All I did was upgrade React Native to 0.74.3 and upgrade some dependencies which were breaking and the problem happened. Moreover, we tried enabling New Architecture, and the problem got even worse.
