I see the same on macOS, but with a different dependency. Copy of error from the emulator: Output of metro bundler: It looks like it's trying to find dependencies at the wrong location. It's looking in |

Did you try: |

@ahardin I will attempt that right now and report back what it does. |
|
It got me past my initial error, but I've run into the same one that I got when I had tried the downgrade route. This error looks like:

Seems to me that this bundler issue is the same as #21490, can you try the workaround described there, and if you recognize that the issue is the same please close this so that we can keep everyone on the other one and avoid redundancy? |

I tried adding babel to the runtime on the most recent release and it's working, and I didn't run into my second error. Will close the issue, but just to be explicit in the report of my solution; my issue was solved by @ahardin's suggestion to:

Replace package.json to: Then follow this steps as is described in Link Go to your project directory and check if this folder exists android/app/src/main/assets From your root project directory do Finally, navigate back to the root directory and check ii) If there are two files i.e Now run |

Description
After following the react-native guide to both setup my react-native app, and my android studio AVD, I have received my current error (I will paste it in full below).
Prior to posting I tried to search around, and couldn't find any recent solutions, or working ones. I had tried downgrading react-native to version 55,2, but ran into other errors. I have also tried the four steps the console produces (clear watchman, delete node_modules, etc). Other than what was installed with react-native init, I have no other dependencies.
package.json:
{
"name": "metronome",
"version": "0.0.1",
"private": true,

"start": "node node_modules/react-native/local-cli/cli.js start",
