`xcrun simctl list` shows nothing

I am a React Native developer. When I run react-native run-ios, the app starts but the simulator doesn't open. I have to open xcode and run the project from there.

When trying to debug this, I noticed that running xcrun simctl list shows nothing. It creates a newline in the terminal and I have to ctrl+c to exit, but the output is nothing.

Thanks, let me know if I should add more info.
Actually, now it lists a bunch of simulators. Weird, it didn't the other day. Still having the React Native issue but I guess that's not for this forum
