[DevTools Bug] Children cannot be added or removed during a reorder operation.

[marinspira]

Website or app

npx react-devtools

Repro steps

I just run npx react-devtools, it recognise my app because does not appear the first page about how to connect it, but I always receive this error even have already checked my FlatList components (I am running React Native Expo development build). And if I close the error, it never loads my components. I receive a "Loading React Element Tree..." in looping.

I have already tried NODE_OPTIONS="--max-old-space-size=4096" react-devtools but still the same error
