react-native android: Debug mode is broken

I think my debug mode for android is kinda broken. I cannot open the debug menu, event though I have yellow-orange boxes for warnings on my device (which tells that i'm running the app on debug mode). No chrome tab opens with a debugger when i run a react-native run-android.

The metro bundler doesn't seem to bundle anything by the way. I used to have a green progress bar but now nothing, even though my app does start on my device.

react-native log-android gives me logs from the app, as if I was looking a the console.

adb shell input keyevent 82 doesn't do anything.

React Native version:

I wasn't able to find anything online on this issue. I don't know what caused that, I've just joined the project and the repository is a mess...

Did you guys had this issue before ?
