Did you configure xRmode in your app.config.js? Android or iOS?

[ThuggerHacks]

I'm using android, I didn't configure anything, I cloned the repo and installed all the packages using npm i, then I started the app using npx expo start

@ThuggerHacks I faced this issue a few days ago while I checked out the latest version of viro with expo 47.
I have not cleaned my package manager cache & installed the latest packages, which might have led to the problem.
Deleted the node_nodules folder, cleaned package manager cache & upgraded to expo 50, did a clean install & it worked again.

I tried it, but the problem persists

Hey, did you try running on development build?

no , ran it on expo go

I think so, the docs say it doesn't support expo go, I don't know if the new release has expo go support, and if you keep having the same problem, I recommend you cloning the starter-kit (ReactNative witg no expo).
