React Native Android App Crash Fixture

I am currently running an Android app, built on the React Native framework, which is currently on version 0.63.4 and I am experiencing an issue with it crashing. I can provide details of the issue, though I am not yet sure of the exact cause. I am looking for an experienced developer to help identify and fix the problem within 24 hours. If you have the necessary skills and expertise to tackle this project, I would be very grateful for your help.
