Cannot read property 'setTitle' of null, js engine: hermes - reactjs

I am getting the following error
while running my React native app.
Things I already tried:
devScripts/set-me-up.sh
deleting node_modules and installing them again
restarting server by reseting cache - npm start -- --reset-cache
but no success yet, any help would be great.


We have to restart with the command react-native run-android .It worked for me,there is no need to removing node modules or cache

installed some dependencies, but now npm start doesn't work

I have a react app that I created with npx create-react-app. I have been workin on this app for a few weeks and decided to try to add a backend. I installed mongoose, express, and nodemon, and I can see them in my dependencies, but now when I use npm start, it opens up my browser and sends me to localhost:3000 but the app doesn't load. just an error saying this site cant be reached, local host refused to connect. Can anyone help me figure out how to get my app properly running again?

Try to delete node modules and install dependencies again similarly you can use npm ci will do the same.

Receiving error when creating new app using create react app

For some reason when trying to create a new app using create react app, it results in errors everytime. Anybody know what's going on?

Have you tried it without the additional --use-npm flags at the end?
npx create-react-app user-onboarding
cd user-onboarding
npm start
Official docs
Edit: Yeah, reading your errors in the screenshot it appears that the --use-npm flag is causing it to use npm which has outdated versions available, but npx always finds the newest versions. Which is a big reason it is the preferred method for installing create-react-app
If you have your heart set on using npm you can always do an npm update before running it again.

Getting stuck on "Downloading Javascript bundle 100.00%" in expo app

Whenever I click 'run in iOS simulator' after running expo start in terminal, I'm getting stuck at a screen with "Downloading Javascript bundle 100.00%" in the app.
I'm creating a React native application and I tried all solutions including:
deleting Expo app
restarting simulator
erasing settings on simulator
rechecking code for bugs
Debug remote JS / stop remote debugging
See example of loading screen:

Delete your package-lock.json file, node_modules directory and then,
run npm cache clean -f.
Then run a new npm install as a regular user.
Finally, run an npm start again

try clearing the cache with expo start -c

Newly created React app crashes on live server

Whenever i create a react app using create-react-app and run npm run start it crashes.
This is the error i am getting in terminal.

(While processing: "/Users/toures/Desktop/REACT/SecondSummit/try1/node_modules/babel-preset-react-app/dependencies.js$0$9")
Can anyone guide me? Thanks.

In the past I've fixed it by deleting the node_modules folder, then running npm install.
