Strange error appearing in React Native: Collection NSSetM was mutated while being enumerated

I started getting strange error in React Native, usually in Modals. Sometimes it works, sometimes it can throw an error: Collections <_NSSetM was mutated while being enumerated.

I am using expo 44.0.0.

Here is my package.json file:

Solution

  • Issue was fixed by downgrading package react-native-reanimated to the previous version and avoiding entering and exiting animations.
