I found the problem the issue is with react-native-maps. Fix is given below

update 

"react-native-maps": "^0.15.2"

to 

"react-native-maps": "0.15.2".

Also I think "^" will cause problem in other dependencies in future. So I have removed them from my Package.json

I had the same problem, Nikhil's answer put me on the right track, unfortunately it was another dependency that was causing the crash.

It took me some time to pinpoint it, here is how I proceeded.

Step 1 : I removed every ^ before dependency's version number in package.json.

Step 2 : add ^ before ONE dependency's version number

Step 3 : remove dependency from node_modules and reinstall it (npm i)

Step 4 : restart package manager and restart application, if it starts without crashing, go to step 2

Optionnal step : Fix the dependency and send a merge request :)

Hope this helps.
