I have tried everything from restarting computer, reinstalling node modules, checking network issues, but I cannot get the metro bundler to start.
These are my diagnostics, if anyone can help it would be much appreciated

This thread ended up being the right answer. Once I switched the command line location and booted up the ios simulator it also started working on my personal device.

I couldn't find anything on the topic, and I am expecting no error.
There was apparently a RN outage. This causes so much issues now as I can get a build out.
https://github.com/facebook/react-native/issues/35210
but that "FIX" says to look at https://github.com/facebook/react-native/issues/35210#:~:text=We%20have%20prepared%20releases%20for%20all%20the%20main%20versions%20of%20react%2Dnative%20with%20an%20hotfix%3A
The issue with that is there is no mention of 0.71.0-RC.0 version fix, I am on that version and when I try to run npx react-native run-android, I get the following:
> Could not find any matches for com.facebook.react:react-native:+ as no versions of com.facebook.react:react-native are available.
If someone came across this could you please mention how you solved this? I do not understand what the fix is for my situation specifically.
This is what the terminal spits out when I run react-native info:

please let me know if I should add more information.
Just to be sure everyone gets this, yes #Grant Solomons got this right.
So if in your package.json file you have "react-native": "^0.70.0",, delete the ^ it to "react-native": "0.70.0",
Fixed by upgrading my RN version to one of the ones with the patches
I have a project I am working on that built yesterday. Today, I am getting this error 'Operator "abs" not found' as seen in the screenshot below. I am not using expo as the build system though the project does use react-native-reanaminated which keeps coming up in my search for a solution and also in this answer React Native Getting this error 'Unrecognized operator abs'.
I tried the solutions there to no avail. Any guidance would be greatly appreciated.

I was able to resolve this by running the following commands.
The first command cleans the ios build in app/ios directory.
The second command resets the simulator. You can also do it from the GUI by clicking Erase All Content and Settings.
❯ cd ios && xcodebuild clean
❯ killall "Simulator" 2> /dev/null; xcrun simctl erase all
Then you rebuild your app as normal with react-native start and open you simulator.
I am trying to create a new react-native project with Expo CLI Quickstart.
expo start --web command is promoting me the below error on macOS.
Cannot destructure property allowedHost of 'undefined' or 'null'.
I tried https://github.com/expo/expo/issues/5727#issuecomment-533895008 but in vain.

I think your xcode are running background on a project that can't be build successfully. Make sure you have opened error free project on xcode(the project can be anything). After doing that see the magic.I don't know why its happening but work for me.
